IntegerScaler — compatibility with games

IntegerScaler is compatible with absolute majority of games that support windowed mode, including those not listed in the table. The table lists games tested personally by the author, it is not a complete list of compatible games. For information about support for windowed mode in other games, see the PCGamingWiki site.

Game Year Windowed mode Border­less DPI-aware Graphics API Engine Note
Settings Alt+Enter
Absolver 2017 ✔️ ✔️ ⚠️ ❌ DirectX 9 UE 4.18.3 Borderless mode is not supported, but windowed mode works similarly at a resolution when the client area of the game window occupies entire screen.
American Truck Simulator 2016 ✔️ ❌ ❌ ✔️ In IntegerScaler 2.7+, Alt+F11 shortcut with this game doesn’t work, it’s needed to trigger delayed scaling before game start, or using IntegerScaler version 2.6 or older, or auto­matic scaling via auto.txt.
ARK: Survival Evolved 2017 ✔️ ❌ ✔️ ❌ DirectX 10 UE 4.5.1
Assetto Corsa 2014 ✔️ ✔️ ⚠️ ❌ DirectX 11

The menu and the game (races) are represented by different executable files.

The menu one (AssettoCorsa.exe) is formally DPI-aware, but the menu is intended for Full HD and gets smaller at higher resolutions (4-times smaller at 4K). The menu always runs in border­less full-screen mode. For Windows to upscale the menu according to OS-level zoom, set the DPI mode for the file to the “System” value.

The game executable (acs.exe) is formally not DPI-aware, but its DPI mode may be automatically switched to the “Application” value by Windows when using in-game 4K resolution together with windowed mode. Over­riding DPI mode of the game executable to the “System” value allows in windowed mode in Windows 10 at integer OS-level zoom, to upscale the game with no blur with no 3rd-party scaler software.

On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at a frame rate of about 60 fps at minimal graphics-quality settings at 4K and at maximum settings at Full HD.
Assetto Corsa Competizione
(version 1.7.10) 		2019 ✔️ ✔️ ✔️ ✔️ DirectX 11 UE 4.22.3 F11 functions in the game like Alt+Enter.
Battletech 2018 ✔️ ✔️ ✔️ DirectX 11 Unity 5.6.6
Big Farm Story
(version 1.3.13236) 		2021 ✔️ ✔️ ✔️ ✔️ DirectX 10 Unity 2020.3.8
Bionic Commando Rearmed 2008 ✔️ ❌ ❌ ❌ DirectX 9c On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution at maximum graphics settings at a frame rate of 60 fps. But works incorrectly at 4K resolution (unrelated to scaling): some elements are invisible on conundrum minilevels “Hack enemy network”, so a lower resolution is necessary. Also, the game lacks anti­aliasing and vertical synchronization (VSync). All these issues are solved with dgVoodoo 2, but at the cost of serious performance impact: on the same system i7-3770T + GTX 650 Ti Boost, frame rate of 60 fps is only achieved at 1920×1080.
Borderlands GOTY Enhanced 2019 ✔️ ✔️ ✔️ ❌ DirectX 9c UE 3
Borderlands 3 2019 ✔️ ✔️ ✔️ ✔️ DirectX 11/12 UE 4.20.3 F11 functions in the game like Alt+Enter.
Bossgard
(Early Access, ) 		2019 ✔️ ✔️ ✔️ ✔️ DirectX 11 Unity 2017.4.25 Full-screen mode is actually borderless.
Broken Sword 5:
The Serpent’s Curse 		2014 ✔️ DirectX 9c There is no resolution in game settings. Resolution in windowed mode is 1280×720 (HD) on FHD monitor and 1920×1080 (FHD) on 4K monitor. After switching between full-screen and windowed modes via settings, the game might hang for up to a minute or crash with a “Couldn't find game assets!” error; the game has three full-screen modes which are switched sequentially, so for switching to windowed mode directly, it’s better to use Alt+Enter.
Brothers: A Tale of Two Sons 2013 ❌ ✔️ ❌ ❌ DirectX 9 UE 3
Burnout Paradise:
The Ultimate Box 		2009 ❌ ❌ ❌ ❌ DirectX 9c On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with 4x antialiasing at a frame rate of about 60 fps, no need to decrease resolution.
Burnout Paradise Remastered 2018 ✔️ ✔️ ✔️ ✔️ DirectX 11 The game blocks keyboard shortcuts of IntegerScaler 2.7+, so it needs delayed scaling or using IntegerScaler 2.6 or older. Also, in border­less mode, scaling built into the game works with no blur with no need for third-party software. But in border­less mode, Windows taskbar is not hidden, so game-window height is lower by the taskbar height, that leads to image distortion; a workaround is to enable automatic taskbar hiding in Windows settings.
Carmageddon: Max Damage 2016 ✔️ ❌ ❌ ❌ DirectX 11
Castle of Illusion 2013 ✔️ ❌ ❌ ❌ DirectX 10/11
Children of Morta
(Pre-release Demo,
Beta Build v0.166.d6) 		2019 ✔️ ✔️ ❌ ✔️ Unity 2017.4.25
Cities XL Platinum 2013 ✔️ ❌ ❌ ❌ DirectX 9c Bitmap user interface decreased proportionally with system-level zoom. In windowed mode, moving over map by moving mouse cursor to edges of game area doesn’t work, but it’s possible to move with arrow keys.
Cities: Skylines 2015 ✔️ ✔️ ✔️ ✔️ DirectX 9c Unity 5.6.6 Full-screen mode is actually borderless. At in-game resolution higher that FHD, user interface of the game (menus, toolbars, messages) is upscaled by the game with blur. The game requires more than 8 GB of RAM, otherwise it hangs or crashes (“Access Violation” error) (unrelated to scaling).
Command & Conquer:
Red Alert 3 		2008 ❌ ❌ ❌ DirectX 9c SAGE 2 Windowed mode can be enabled with the command-line parameter -win. In windowed mode, moving over map by moving mouse cursor to edges of game area doesn’t work, but it’s possible to move with arrow keys or by moving mouse while holding down its right button.
Command & Conquer 4:
Tiberian Twilight 		2010 ❌ ❌ ⚠️ DirectX 9c SAGE 2
Commandos 2:
Men of Courage 		2002 ❌ ✔️ DirectX 9 In windowed mode, moving over map by moving mouse cursor to edges of game area doesn’t work.
Commandos 3:
Destination Berlin 		2003 ❌ ❌ DirectX 9
Conan Exiles 2018 ✔️ ✔️ DirectX 11 UE 4 The game uses F11 for switching between windowed and full-screen modes, delayed scaling via IntegerScaler menu is required.
Conan Unconquered 2019 ✔️ ✔️ ⚠️ ❌ DirectX 11 In border­less mode (“Full-Screen Borderless Window”) with DPI mode “System”, moving over map to the right and bottom by moving mouse cursor to edges of game area doesn’t work, but it’s possible to move with arrow keys. This does not affect windowed mode.
Counter-Strike: Global Offensive
(CS: GO) 		2012 ✔️ ❌ ❌ ✔️ Source Borderless mode is supported (“Fullscreen Windowed”), but can’t be used for scaling — the game works at full desktop resolution even at the “System” DPI-mode. So windowed mode in conjunction with scaling via IntegerScaler should be used.
Cyberpunk 2077 2020 DirectX 12 The game uses DirectX 12, so there is blur when scaling via IntegerScaler (Windows-level limitation).
Darkest Dungeon 2016 ✔️ ❌ ✔️ ✔️ OpenGL 3.2 Full-screen mode is actually borderless. Windowed mode operates as border­less if game resolution is equal to screen resolution. The native game resolution is 1920×1080, the game uses blurry scaling at other resolutions.
Days of War: Definitive Edition 2020 ✔️ ✔️ ✔️ ❌ DirectX 11/12 UE 4.20.3
DayZ 2018 ✔️ ✔️ ✔️ ❌ DirectX 11 Windowed mode operates as border­less if game resolution is equal to screen resolution, but only immediately after switching resolution via game settings; after restarting the game, window has borders and a wrong size with image distortion.
Dead by Daylight 2016 ✔️ ✔️ ❌ DirectX 11 UE 4.21.1 Impossible to specify resolution explicitly via game settings, only resolution scaling via a % value. Resolution can be specified via command-line parameters -resx and -resy, e. g.: -resx=1920 -resy=1080.
Deep Rock Galactic
(Early Access, version 0.24.30509.0,
) 		2018 ✔️ ✔️ ✔️ ❌ UE 4.21.2
Descenders 2019 ✔️ ✔️ ✔️ ✔️ DirectX 11 Unity 2017.4.9 The game has low-quality anti­aliasing, so the game looks bad at FHD resolution. When started in exclusive full-screen mode, switching between windowed and full-screen modes may work incorrectly (unrelated to scaling).
DiRT 2 (Colin McRae: DiRT 2) 2009 ❌ ✔️ ❌ ✔️ DirectX 9c/11 EGO 1
DiRT 3 2011 ❌ ✔️ ❌ ❌ DirectX 9c/11 EGO 2
Disintegration 2020 ✔️ ✔️ ✔️ ❌ UE 4.22.2
DOOM (Demo) 2016 ✔️ ✔️ ✔️ ✔️
Dota 2 2013 ✔️ ❌ ✔️ ✔️
Driver: San Francisco 2011 ✔️ ❌ ❌ ❌ DirectX 9c On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution at maximum graphics settings at a frame rate of 60 fps, no need to decrease resolution.
DuckTales Remastered 2013 ❌ ✔️ ✔️ ❌ DirectX 9c Does not always resize game window according to in-game resolution. Game restart is required for resolution to apply. The game is always rendered at Full HD resolution and uses internal scaling at other resolutions. Sometimes works with no blur under Windows 10 even without 3rd-party scaler software. Full-screen mode is actually borderless.
Dungeon of the Endless 2014 ✔️ ❌ ⚠️ ✔️ DirectX 9c Unity 5.0.3 Full-screen mode is actually borderless. Alt+Enter formally works, but in fact incorrectly — window occupies entire screen regardless of in-game resolution. The game has built-in nonblurry scaling, but menu and controls get smaller at higher resolutions; when using full-screen (borderless) mode for scaling with Windows’ built-in DPI scaling, moving over map by moving mouse cursor to edges of game area doesn’t work sometimes; so for convenience, it’s necessary to use scaling via third-party software like IntegerScaler.
Endless Legend 2014 ✔️ ✔️ ✔️ ✔️ DirectX 9c Unity 5.3.6 Full-screen mode is actually borderless. In windowed mode, moving over map by moving mouse cursor to edges of game area doesn’t work, but it’s possible to move with arrow keys.
Endless Space 2 2017 ✔️ ⚠️ ✔️ ✔️ DirectX 11 Unity 5.5.1 There is a setting in the game to limit the area of mouse-cursor movement by the game window, disabled by default: “Options” → “Video” → “Lock Cursor”; the limitation may work incorrectly after switching between windowed and full-screen modes via Alt+Enter (unrelated to scaling). After switching from border­less mode to windowed mode, window has a wrong size (unrelated to scaling), game restart or switching to a different resolution and back helps.
Euro Truck Simulator 2 2012 ✔️ ❌ ❌ ✔️ In IntegerScaler 2.7+, Alt+F11 shortcut with this game doesn’t work, it’s needed to trigger delayed scaling before game start, or use IntegerScaler version 2.6 or older. Automatic scaling via auto.txt might not work.
F1 2015 2015 ✔️ ✔️ ❌ ❌ DirectX 11 EGO 3
F1 2018 2018 ✔️ ✔️ ✔️ DirectX 11 EGO 3
F1 2019 2019 ✔️ ⚠️ ✔️ ❌ DirectX 11 EGO 3 Alt+Enter may lead to minimizing the game with no way to restore it (unrelated to scaling). Border­less mode is called “Windowed (Fullscreen)”.
F1 2020
(version 1.12) 		2020 ⚠️ ⚠️ ✔️ ❌ DirectX 11/12 EGO Switching between windowed and full-screen modes may lead to minimizing the game with no way to restore it (unrelated to scaling); minimizing all via Win+D, then switching to game window helps. Border­less mode is called “Windowed (Fullscreen)”.
Fallout 76 2018 ✔️ ❌ ✔️ ✔️ DirectX 11 Creation
Faster Than Light (FTL)
(version 1.6.12) 		2012 ✔️ ❌ ✔️ ✔️ OpenGL 2.0 The game formally supports border­less mode (“Stretch”), but it can’t be used for scaling: the game window is cropped. The native resolution of the game is 1280×720, integer-ratio scaling is only possible on QHD+ (2560×1440 and higher) displays.
FlatOut: Ultimate Carnage 2008 ✔️ ❌ ❌ ❌ DirectX 9c
FlatOut 4: Total Insanity 2017 ✔️ ✔️ ✔️ ❌ DirectX 11
Football Manager 2020 2019 ✔️ ⚠️ ✔️ ✔️ DirectX 11 Full-screen mode is actually borderless. After switching from windowed mode to full-screen mode with Alt+Enter, game resolution sets to 2048×1536 regardless of one previously selected via game settings. In windowed mode on 4K monitor, minimum possible window size corresponds to resolution of 2028×1516, so ratio is below 2.0 (200%), and using IntegerScaler for scaling does not make sense. Resolution of 3D graphics is implicitly controlled via “This PC’s 3D Graphics Capability” dropdown in game settings, where with 4K monitor, 4K resolution corresponds to “Very High” item.
Frostpunk 2018 ✔️ ❌ ✔️ ✔️ DirectX 11 Liquid Engine Alt+F11 does not work in IntegerScaler 2.7+, but works in previous versions. Delayed scaling works, via Ctrl+Alt+F11 or IntegerScaler menu; auto­scaling with auto.txt works too.
Gas Guzzlers Extreme 2013 ✔️ DirectX 9c/11
Generation Zero 2019 ✔️ ✔️ ✔️ ❌ DirectX 11 Apex Game restart is needed after switching to windowed mode, otherwise window size is wrong.
Giana Sisters: Twisted Dreams 2012 ✔️ ❌ ❌ DirectX 9/10
Giana Sisters: Twisted Dreams —
Rise of the Owlverlord 		2013 ✔️ ❌ ❌ DirectX 9/10
Grand Theft Auto IV
(GTA IV, GTA 4) 		2008 ❌ ✔️ ✔️ DirectX 9c The Alt+Enter keyboard shortcut formally switches the game to windowed mode, but the window size is multiple times smaller than the resolution set in game settings. Proper windowed mode can be enabled via the -windowed command-line parameter. But window size is then slightly smaller than the in-game resolution, e. g. at the resolution of 1920×1080, window size is 1898×1069, and its client area (the area where the game itself is rendered) is 1894×1009. This results in image distortion. Also, the game stutters every several seconds (unrelated to scaling). So it’s impossible to play comfortably.
Grand Theft Auto V
(GTA V, GTA 5) 		2015 ✔️ ✔️ ✔️ ❌ DirectX 10/10.1/11
GRID (Race Driver: GRID) 2008 ❌ ❌ ❌ ❌ DirectX 9c EGO 1 Windowed mode can be enabled by setting the fullscreen attribute to false value instead of true in hardware_settings_config.xml file in [DOCUMENTS]\Codemasters\GRID\hardwaresettings folder.
GRID (2019) 2019 ✔️ ✔️ ✔️ ✔️ DirectX 11/12 EGO
GRID Autosport 2014 ✔️ ✔️ ❌ ❌ DirectX 11 EGO 3
Grim Dawn 2016 ✔️ ⚠️ ✔️ ✔️ DirectX 9c/11 In windowed mode, client-area size of the game window is slighly smaller than in-game resolution, so the image is distorted; Border­less mode is not affected. Alt+Enter works incorrectly: the game gets minimized, and it can only be restored by pressing Alt+Enter again during a short period of showing dark screen after clicking on the game in Windows Taskbar. The game menu gets smaller at resolutions higher than FHD; the “UI Scale” setting only applies to user interface during gameplay.
GRIP: Combat Racing 2018 ✔️ ✔️ ✔️ ❌ DirectX 11 UE 4.17.2 The game uses F11 for switching between windowed and full-screen modes, delayed scaling via IntegerScaler menu is required.
Grounded
(Early Access, version 0.4.2.2656,
) 		2020 ✔️ ✔️ ✔️ ❌ UE 4.25 The game uses F11 for switching between windowed and full-screen modes.
Half-Life 2 2004 ✔️ ❌ ❌ ⚠️ DirectX 8.1 Source On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with no anti­aliasing at a frame rate of about 60 fps, no need to decrease resolution. But user-interface size is tied to physical pixels, so interface gets smaller relative to screen at higher resolutions. After switching to windowed mode, mouse-cursor position visible by the game is slightly shifted down compared with its actual position; the issue does not reproduce after restarting the game.
Hell Let Loose
(Early Access, version 1.3.601504,
) 		2019 ✔️ ✔️ ✔️ ❌ DirectX 11 UE 4.21.2
Hitman 2 2018 ✔️ ✔️ ✔️ ✔️ DirectX 11 Size of the client area (the area where the game itself is rendered) of the game window is slightly smaller than in-game resolution, e. g. at the resolution of 1920×1080, the client-area size is 1904×1064.
Horizon Chase Turbo 2018 ✔️ ✔️ ✔️ ✔️ DirectX 9c Unity 2018.4.27 Full-screen mode is actually borderless. On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with 2x antialiasing at a frame rate of about 60 fps, no need to decrease resolution for the purpose of increasing performance.
Hunt: Showdown
(Early Access, version 1.6.1.656,
) 		2018 ✔️ ⚠️ ✔️ ✔️ DirectX 11 CryEngine 5.4 Switching between windowed and full-screen modes with Alt+Enter works incorrectly.
Insurgency: Sandstorm 2018 ✔️ ✔️ ✔️ ✔️ DirectX 11 UE 4.22.1
Just Cause 2 2010 ✔️ DirectX 10
Killer Instinct
(version KI:3.11.31118.1.295559.r) 		2017 ✔️ ❌ ❌ ✔️ ⚠️ DirectX 11 Slayer There is blur when scaling via IntegerScaler though formally the game uses DirectX 11. DirectX 12 is probably used instead of DirectX 11 on systems with DirectX 12 support.
Killing Floor 2 2016 ✔️ ✔️ ✔️ ❌ DirectX 10/11 UE 3 After switching the game between windowed and full-screen modes with Alt+Enter, game resolution may switch to native monitor resolution (unrelated to scaling).
Lara Croft and the Guardian of Light 2010 ❌ ❌ ❌ ❌ DirectX 9c On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with antialiasing disabled at a frame rate of about 60 fps, no need to decrease resolution.
Lara Croft and the Temple of Osiris 2014 ✔️ ✔️ ✔️ ❌ DirectX 11 In windowed mode, changing game resolution is not available in game settings, use -resize command-line option of IntegerScaler, or use borderless mode for scaling.
Left 4 Dead 2 2009 ✔️ ❌ ✔️ ❌ DirectX 9c Source On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K with 4x AA with a frame rate of about 60 fps, and user interface of the game is properly scaled; no need to decrease resolution.
Mafia III 2016 ✔️ ✔️ ❌ ❌ DirectX 11
MDK (Windows version, GOG) 1997 ❌ ❌ The game has a fixed resolution of 640×480; the game settings don’t allow to change resolution. But using 3dfx version of the game, it’s possible to change resolution via nGlide emulator settings. On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with a frame rate of about 60 fps, no need to decrease resolution.
Mirror’s Edge 2009 ❌ ❌ ❌ ❌ DirectX 9c UE 3 It’s possible to switch the game to windowed mode with the DxWnd app.
Mortal Kombat 1 2023 DirectX 12 UE 4.27.2 Game uses DirectX 12, so there is blur when scaling via IntegerScaler (Windows-level limitation).
Mortal Kombat Komplete Edition 2013 ❌ ❌ ❌ ❌ DirectX 10/11 UE 3 It’s possible to switch the game to windowed mode with the DxWnd app.
Mortal Kombat X (XL) 2015 ✔️ ✔️ ❌ DirectX 11 UE 3 (модиф.)
Moto Racer 4 2016 ✔️ ⚠️ ❌ DirectX 11 UE 4.16.2 The game uses F11 for switching between windowed and full-screen modes, delayed scaling via IntegerScaler menu is required. Alt+Enter works not always correctly: sometimes the game, instead of switching to full-screen mode, switches to a border­less window of a size matching in-game resolution; and sometimes, after retiring from a race, the game unexpectedly switches from full-screen mode to windowed mode if full-screen mode was enabled before via Alt+Enter.
nail’d 2010 ✔️ ❌ ⚠️ ❌ DirectX 9c CE 4 Borderless mode is not supported, but windowed mode works similarly at a resolution when the client area of the game window occupies entire screen. The game might crash after changing graphics settings (unrelated to scaling), but after restart, works correctly with previously chosen settings applied.
NASCAR Heat 4 2019 ✔️ ✔️ ✔️ ✔️ DirectX 11 Unity 2017.4.28 Full-screen mode is actually borderless.
Need for Speed 2016 ✔️ ✔️ ❌ ❌ DirectX 11 Frostbite In windowed mode, changing game resolution is unavailable, but resolution changes according to window size that can be changed via the -resize parameter of IntegerScaler.
Need for Speed: Hot Pursuit 2010 ❌ ❌ DirectX 9c
Need for Speed: Most Wanted 2012 ❌ ✔️ ❌ ✔️ DirectX 10/11
Need for Speed Payback 2017 ✔️ ✔️ ❌ ❌ DirectX 11 Frostbite In windowed mode, changing game resolution is unavailable, but resolution changes according to window size that can be changed via the -resize parameter of IntegerScaler.
Need for Speed Rivals:
Complete Edition 		2013 ✔️ ❌ ❌ ❌ DirectX 11 Frostbite The game has low-quality anti­aliasing and does not have AA-related settings, so the game looks bad at FHD resolution.
Oddworld: Munch’s Oddysee 2010 ❌ ✔️ ❌ ❌ DirectX 8 / OpenGL 2 Doesn’t have a setting for changing resolution. In full-screen mode, runs at system (desktop) resolution. Windowed-mode resolution is 640×480.

Rayman Legends 2013 ✔️ ❌ ❌ ❌ DirectX 9c
Redout 2 (Redout II) 2022 ✔️ ✔️ ⚠️ ❌ DirectX 12 UE 4.27.2 Game uses DirectX 12, so there is blur when scaling via IntegerScaler (Windows-level limitation). Same when scaling via “Borderless” mode. F11 functions in the game like Alt+Enter.
Risk of Rain 2
(Early Access, version 4811921,
) 		2019 ✔️ ✔️ ✔️ ✔️ DirectX 11 Unity 2018.4.16 Full-screen mode is actually borderless. There is no anti­aliasing of 3D graphics in the game.
Road Redemption 2019 ✔️ ❌ ⚠️ ✔️ DirectX 9/11 Unity 2017.4.32 The game runs much slower in windowed mode compared with full-screen mode (unrelated to scaling). Full-screen mode when starting in “standard” mode is actually borderless.
Rocket League

Sonic Generations 2011 ❌ ❌ ❌ DirectX 9c
Space Engineers
(version 1.196.018, ) 		2019 ✔️ ❌ ✔️ ✔️ DirectX 11 VRage In borderless (“Full­screen window”) mode, scaling is done by the game and is nonblurry with no need for third-party software.
Split/Second: Velocity 2010 ❌ ❌ DirectX 9c
Star Citizen
(Alpha 3.10.2) 		2020 ✔️ ✔️ ✔️ ⚠️ DirectX 11 ALY Alt+F11 does not work in IntegerScaler 2.7+, but works in 2.6 and older. During game­play, the F11 key shows/hides a menu. When switching between full-screen, windowed and border­less modes, the game might stick to windowed mode or minimized state. In border­less mode (“Full­screen Windowed”), game window is not stretched to entire screen if logical resolution is lower than desktop resolution. Game loading takes minutes, and the game crashes a lot (unrelated to scaling).
Starsector
(version 0.9.1a-RC8) 		2019 ✔️ ❌ ❌ ⚠️
Steel Rats 2018 ✔️ ✔️ ✔️ ❌ DirectX 11 UE 4.19 The game uses F11 for switching between windowed and full-screen modes, delayed scaling via IntegerScaler menu is required. Full-screen mode is actually borderless.
Stellaris 2016 ✔️ ❌ ✔️ ❌ User interface is bitmap-based and gets smaller at higher resolutions. There is “UI Scaling” setting with values in the 1.0–3.0 range with the step of 0.1 (game restart is needed after changing it) that results in that user interface is blurrily upscaled by the game.

Tom Clancy’s Rainbow Six Siege 2015 ✔️ ✔️ ✔️ ❌ DirectX 11
Tom Clancy’s The Division 2 2019 ✔️ ✔️ ❌ ✔️ DirectX 11/12 Snowdrop The game formally supports border­less mode (“Windowed (Fullscreen)”), but it can’t be used for scaling: game resolution in this mode is forcedly set to desktop resolution with no ability to change it, and game window is enlarged propor­tionally with OS-level zoom and doesn’t fit screen.
Tomb Raider: Anniversary 2007 ❌ ❌ ❌ DirectX 9c On a system based on i7-3770T + GTX 650 Ti Boost, the game runs at 4K resolution with 8x antialiasing at a frame rate of about 60 fps, no need to decrease resolution.
TrackMania² Stadium 2013 ✔️ ✔️ ✔️ ❌ DirectX 11 In windowed mode, it’s needed to manually specify width and height of game window via game settings. Border­less mode is called “WindowedFull”.
Trine Enchanted Edition 2014 ✔️ ❌ ❌ ❌ DirectX 9c To enable windowed mode, choose “Run in window” in second dropdown in “Screen resolution and refresh rate” section of game-launcher window.
Trine 2 2013 ✔️ ❌ ❌ ❌ DirectX 9c
Tropico 6 2019 ✔️ ✔️ ⚠️ ✔️ DirectX 11 UE 4.20.2 When scaling with border­less mode in con­junction with Windows’ DPI scaling, moving over map by moving mouse cursor to edges of game area only works if cursor is near the edge, but does not touch it. Scaling with IntegerScaler is not affected.
TT Isle of Man: Ride on the Edge 2 2020 ✔️ ✔️ ✔️ ❌ DirectX 11
Two Point Hospital 2018 ✔️ ✔️ ✔️ ✔️ DirectX 11 Unity 2018.4.2 Full-screen mode is actually borderless.
Unreal Gold (GOG version) 1999 ❌ ⚠️ In windowed mode, the game runs too fast (unrelated to scaling).
Urban Trial Freestyle 2013 ⚠️ ❌ ❌ ❌ DirectX 9 In windowed mode, a limited set of resolutions is available in the game. The highest one on 4K monitor is 1600×1200. The one closest to FHD is 1280×960 (4:3; 2x enlargement on 4K monitor). Highest one with the 16:9 ratio is 1280×720 (3x enlargement on 4K monitor). It’s possible to set a custom resolution such as 1920×1080, via manual editing of the parameters -w and -h in the file %LOCALAPPDATA%\Urban Trial Freestyle\user-v2.ini or via command line: -w=1920 -h=1080.
Watch Dogs: Legion 2020 ✔️ ✔️ ✔️ ✔️ DirectX 11/12
WRC 6 2018 ✔️ ✔️ ✔️ ❌ DirectX 11 After switching from full-screen mode to windowed mode, the game window has a smaller size than should according to game resolution, so game resolution should be changed after switching to windowed mode.

Z 2014 ✔️ Real game resolution is unknown, there is blur regardless of resolution chosen via game settings. By default (unrelated to scaling) the game on 4K monitor works incorrectly, it’s required first to run it on a monitor with a lower physical resolution.

The following conventions are used in the table:

  • Windowed mode:
    • Settings — the game settings allow switching to windowed mode.
    • Alt+Enter — switching to windowed mode is possible via the Alt+Enter keyboard shortcut.

  • Borderless — the game supports the so called “Borderless” mode. Overriding DPI mode for the executable file (*.exe) of such a game to the “System” value allows in this mode in Windows 10 at integer OS-level zoom (e. g. 2.0 = 200%), to upscale the game with no blur with built-in means of Windows 10 with no need for 3rd-party scaler software like IntegerScaler.

    The limitations of the scaling method based on the “Borderless” mode:

    • The ratio is always equal to the OS-level zoom. So upscaling FHD to 4K needs the OS-level zoom of 200%, while upscaling HD to 4K needs the OS-level zoom of 300%. Unlike the “Borderless” mode, IntegerScaler supports arbitrary scaling ratios calculated auto­matically and recalculated dynamically depending on window size with no need for changing system settings.
    • Borderless-based scaling with no blur is solely available in Windows 10. IntegerScaler supports Windows 7+.

  • DPI-aware — the game is compatible with HiDPI (High DPI) modes. For HiDPI-incompatible games at system-level zoom higher than 100% (not to be confused with scaling with IntegerScaler), it’s necessary to disable DPI virtua­lization (DPI scaling) in properties of the game executable-file, otherwise there will be blur anyway, or the game window might be invisible when scaling is enabled (e. g. in “Driver: San Francisco”).

    When running a game via the Steam client application, the result might depend on operating system: Steam supports HiDPI under Windows 10, so some games might inherit its DPI mode, so disabling DPI virtua­lization manually for the game is unneeded in such cases. But in older Windows versions including Windows 7, Steam does not support HiDPI, so it might be necessary to disable DPI virtuali­zation for the same game.

    For some games formally not declared as DPI-aware, Windows may automatically disable DPI scaling in executable-file properties, after switching the game to windowed mode. So in some cases, the game may be scaled with no blur at first start, even without manually disabling DPI scaling.
