Windows 11 includes a setting called Optimizations for windowed games, and its name is less useful than its function. It changes how many DirectX 10 and DirectX 11 games present frames when they run in windowed or borderless-windowed mode. In the right game, that can reduce frame latency and make Variable Refresh Rate or Auto HDR available.
For most players, the answer is straightforward: leave it on unless a specific older game develops visual problems, crashes, or feels worse. The feature can be disabled per game, so one troublesome title does not require turning it off system-wide.
What the setting actually changes
According to Microsoft’s Windows support documentation, the setting moves compatible DX10 and DX11 windowed games from the older bit-block transfer presentation model to the modern flip model.
That technical change matters because the flip model lets a completed frame reach the display more directly. It can reduce the extra latency historically associated with borderless-windowed play and allows supported games to use two display features:
- Variable Refresh Rate: A compatible monitor can synchronize its refresh timing with the game’s frame delivery to reduce tearing and judder.
- Auto HDR: Windows can expand the apparent brightness and color range of supported SDR games on an HDR display.
This is not a universal FPS booster. It changes frame presentation, not the speed at which a CPU or GPU renders the scene. If a game is limited by shader compilation, asset streaming, or a slow processor, this switch will not remove the underlying bottleneck. Our guides to shader compilation stutter and DirectStorage explain those separate problems.
Which games benefit?
The main targets are older DX10 and DX11 titles running in a window or borderless window. Many newer DX12 games already use modern presentation paths, so the setting may make no meaningful difference to them. Exclusive-fullscreen games also follow a different path.
The most noticeable benefit is often input responsiveness in a borderless game, especially when a player frequently uses Alt+Tab, streams from the same PC, or keeps chat and monitoring tools on another display. VRR users may also see smoother motion when the frame rate moves within the monitor’s supported range.
Results vary by game and driver. A title with an unusual overlay, capture hook, or anti-cheat implementation may behave differently. Treat the setting as a compatibility upgrade with potential latency benefits, not as a guaranteed benchmark gain.
How to enable it in Windows 11
- Open Settings.
- Select System, then Display.
- Choose Graphics.
- Open Default graphics settings.
- Turn on Optimizations for windowed games.
- Restart any game that was already open.
The wording can vary slightly between Windows 11 builds, but the control remains under the Graphics settings. Microsoft also notes that enabling Auto HDR automatically enables windowed game optimizations because Auto HDR depends on the modern presentation path.
How to disable it for one problem game
If a title begins flickering, shows unusual frame pacing, fails with an overlay, or crashes after the change, disable the feature only for that executable:
- Return to Settings > System > Display > Graphics.
- Select the game from the app list. Add its executable if it is missing.
- Open Options.
- Check Don’t use optimizations for windowed games, then save.
- Restart the game and compare the same scene and frame-rate cap.
If Auto HDR is enabled for that game, turn Auto HDR off as well before judging the result. Microsoft says the optimization cannot stay disabled while Auto HDR is active.
The practical verdict
Keep the setting enabled globally if you play borderless DX10 or DX11 games. It can provide lower presentation latency and unlock VRR without forcing exclusive fullscreen, and Windows offers a clean per-app escape hatch for compatibility problems. Just do not mistake it for a cure-all performance toggle. Smooth gaming still depends on stable frame times, correct drivers, sensible graphics settings, and hardware that can render the workload.
