Turn off Game Bar background recording

Stops Xbox Game Bar from continuously recording the last minutes of gameplay.

Applying it needs Nexus Standard or Pro. Every plan can read it here and undo it in Restore Center. Compare plans

What it changes

Sets HKCU\Software\Microsoft\Windows\CurrentVersion\GameDVR\HistoricalCaptureEnabled = 0 (Settings > Gaming > Captures > 'Record what happened').

Before anything is written, the review screen shows this setting's current value on your PC next to the new one.

Why it helps

Background recording keeps a video encoder running while you play; Windows' own settings page warns that it can affect game performance. Turning it off removes that work.

Trade-offs

You can no longer save a clip of what just happened (Win+Alt+G). Manual recording still works.

Evidence

Strong evidenceExpected impact:Noticeable

Strong evidence means: documented by microsoft or consistently measurable. Expected impact is noticeable (2 of 3): how much it can matter when this is actually the bottleneck on your PC, not a promised gain.

Is it in a pack?

Yes. It's in the Gaming performance pack, so that pack and Optimize everything include it. You can still untick it in the review screen.

How to undo

Switch the tweak off in Nexus, or open Restore Center and restore this change (or choose Undo last change). Nexus writes back the original value it recorded before applying, not a generic default, then reads it back to confirm.

Preview the exact change, apply it with its original value recorded, and undo it in one click if you change your mind.
