What this section changes
Reduces the time the display driver and desktop compositor take away from the game.
| Setting | What it does | Registry path |
|---|---|---|
| Restore the display-driver timeout to the Windows default | Deletes TdrDelay so Windows uses its own 2-second timeout. That timeout is how long Windows waits before rescuing a graphics card that stopped responding — raising it does not make anything faster, it only makes a stall last longer, with no picture, cursor or input for the whole time. Earlier builds of w0a set 10 s here; this puts it back. | HKLM\...\GraphicsDrivers\TdrDelay |
| Turn off window animations | Window and taskbar animations are drawn on the same GPU the game uses; alt-tab becomes instant (transparency is its own tweak on the Optimizations page) | HKCU\...\WindowMetrics\MinAnimate + Explorer\Advanced\TaskbarAnimations |
Applying it
- Open w0a
- Go to the Regedit Tweaks page in the left menu
- Find this section, tick the settings you want, apply
Every setting is individually selectable — you are not required to apply a whole section.
Undoing it
Two ways, both of which work:
- Backups & Restore — puts back the checkpoint written before the change was applied. It
reverts what that group changed and touches nothing else.
- The Fix page — searched by symptom, writes the Windows default unconditionally. It does not
read a backup, so it works even if w0a's own backup file is gone.
The undo log lives at %ProgramData%\w0a\backup.json, outside your user profile.
The risk
Everything here is a documented value Windows supports; none of it is kernel-level and none of it is irreversible. The honest sentence is still this: a setting may have no measurable benefit for you. If you apply a change and feel no difference, you are probably right — these pages are not selling you a feeling, they are telling you what was changed.
If you want to measure it, the rule from reading the benchmark applies: change one thing at a time, and read the lows rather than the average.
