What is optimizations for windowed games in Windows 11?
If you play PC games in borderless windowed mode, Windows 11 includes a dedicated graphics setting called Optimizations for Windowed Games. Historically, running a game in windowed or borderless mode forced Windows to route every frame through the Desktop Window Manager (DWM) using an older presentation technique known as BitBlt. This added a buffer frame, causing noticeable input delay and inconsistent frame pacing compared to exclusive fullscreen mode.
Optimizations for windowed games solves this bottleneck by upgrading legacy DirectX 10 and DirectX 11 titles to the modern DXGI Flip Model. Instead of copying frame buffers repeatedly, the graphics card flips the finished frame directly onto the screen. This gives you the speed and low latency of exclusive fullscreen while keeping the instant multitasking benefits of borderless windowed play.
Should you turn optimizations for windowed games on or off?
For almost all modern gaming setups, you should keep Optimizations for Windowed Games turned ON. Microsoft introduced this feature in Windows 11 version 22H2, and it delivers three clear advantages for gamers:
-
Lower display latency: Eliminates the extra frame buffer delay in DirectX 11 borderless titles, bringing response times on par with exclusive fullscreen.
-
Auto HDR support: Unlocks Windows Auto HDR for older DirectX 10 and 11 games that previously required exclusive fullscreen.
-
Better Variable Refresh Rate (VRR): Allows G-Sync and FreeSync to engage smoothly without screen tearing when switching between background apps and your game.
However, if you run multiple monitors with widely different refresh rates (such as a 240Hz primary panel paired with a 60Hz secondary display) or play older modded games, you may occasionally experience frame pacing jitter due to GPU driver overlay conflicts. In those rare scenarios, you can disable the setting globally or set a per-app override.
| Setting | Recommended Value | Why |
|---|---|---|
| Optimizations for Windowed Games | On (Default) | Upgrades DX11 windowed games to the low-latency Flip Model. |
| Variable Refresh Rate (VRR) | On | Maintains seamless G-Sync and FreeSync pacing in borderless mode. |
| Hardware-Accelerated GPU Scheduling (HAGS) | On | Reduces CPU scheduling overhead for graphics frame submission. |
| Windows Game Mode | On | Allocates maximum CPU threads to active game processes. |
How to enable or disable optimizations for windowed games
Windows 11 enables this feature automatically on clean installations, but you can check your system configuration with these steps:
-
Press Windows Key + I to open the Settings menu.
-
Navigate to System > Display > Graphics.
-
Under the “Default settings” section, click Change default graphics settings.
-
Locate the toggle labeled Optimizations for windowed games and switch it to On.
-
Restart your PC or restart your running game to apply the change.
How to set per-game overrides in Windows 11
If a specific title suffers from micro-stutters or crashes after enabling this feature, you do not need to turn it off for your entire library. Windows allows you to exempt individual titles:
Go to Settings > System > Display > Graphics, locate your specific game executable from the app list (or click “Browse” to add its .exe file), click Options, and check the box to disable windowed optimizations for that specific title alone.
Input latency comparison: Borderless vs exclusive fullscreen
Competitive players frequently debate whether borderless windowed mode is ready for high-stakes ranked matches. When you test system latency with high-speed cameras or latency analyzers, traditional borderless mode carried an input lag penalty of 10ms to 20ms. With Optimizations for Windowed Games active, that gap narrows to less than 1ms.
If your goal is absolute minimum input latency, fine-tuning display composition is only one part of the equation. You also need to clean background interrupt queues, tune USB polling rates, and apply proven PC tweaks for gaming. You can explore deeper latency tuning in our complete guide to reduce input lag in competitive games.

USB polling rate directly determines your minimum input lag. Higher = faster response.
Does this setting affect DirectX 12 and Vulkan games?
A common misconception among PC gamers is that toggling this feature will change performance in titles like Cyberpunk 2077 or Valorant. It will not. DirectX 12 and Vulkan graphics APIs were designed from the ground up to use modern flip presentation models natively. These modern APIs bypass the legacy DWM compositor automatically regardless of whether the Windows toggle is on or off.
The feature specifically targets titles built on DirectX 10 and DirectX 11, such as Apex Legends, Rainbow Six Siege (DX11 mode), League of Legends, Counter-Strike 2 in windowed configurations, and countless older esports games.
Troubleshooting micro-stutters and multi-monitor issues
If you experience frame drops after turning this feature on, the culprit is usually Multi-Plane Overlay (MPO) instability in GPU drivers. When running hardware-accelerated apps (like Discord, Spotify, or web browsers) on a secondary screen alongside a borderless game, the GPU display engine can desynchronize refresh cycles.
To resolve this without losing windowed optimizations:
-
Disable hardware acceleration inside Discord and your web browser settings.
-
Update your graphics card drivers to the latest clean release using DDU (Display Driver Uninstaller).
