1. The Golden Rule: Create a Backup
DANGER: Incorrectly modifying the registry can cause system instability or prevent Windows from booting. Follow instructions exactly as written.
- Press Win + R, type
regeditand hit Enter. - In the Registry Editor, go to File → Export.
- Under Export Range (bottom left), select All.
- Save the file to a safe location (e.g., your Desktop) as "Backup.reg". If anything goes wrong, double-click this file to restore.
2. Disable GameDVR / GameBar
Windows GameDVR often causes micro-stutters and forces "Fullscreen Optimizations" which add input delay.
- In Registry Editor, navigate to:
Computer\HKEY_CURRENT_USER\System\GameConfigStore - Double-click on GameDVR_Enabled and change the Value data to
0. - Double-click on GameDVR_FSEBehaviorMode and change the Value data to
2. - Next, navigate to:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\GameDVR(If the "GameDVR" folder doesn't exist, right-click "Windows", select New > Key, and name it GameDVR). - Right-click inside the GameDVR folder, select New > DWORD (32-bit) Value, name it
AllowGameDVR, and set the value to
0.
3. UI Responsiveness (MenuShowDelay)
By default, Windows adds a 400-millisecond delay to menus. Lowering this makes the OS feel instantly snappy.
- Navigate to:
Computer\HKEY_CURRENT_USER\Control Panel\Desktop - Find the value named MenuShowDelay.
- Double-click it and change the Value data from "400" to
10. (Setting it to 0 can sometimes cause graphical glitches).
4. CPU Priority for Gaming (SystemProfile)
This tweak forces Windows to allocate more CPU resources to foreground applications (your games) rather than background tasks.
- Navigate to:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile - Double-click NetworkThrottlingIndex and set Value data to
ffffffff(Hexadecimal). - Double-click SystemResponsiveness and set Value data to
10. - Now expand SystemProfile and click on the Tasks folder, then click on the
Games folder:

- GPU Priority:
8 - Priority:
