Turn off background recording (Game DVR) in Windows
Xbox Game Bar can keep recording the last minutes of your game in the background, so you can save a clip after something happened. That recording costs graphics card time, memory and disk writes all the time.
What it costs#
Modern graphics cards encode video with a separate chip, so the cost is usually small. It's not zero: recording uses video memory and writes to the disk constantly. On weaker PCs and laptops, that can show up as lower frame rates or short hitches.
What to keep#
Turning off background recording doesn't remove Game Bar. You can still take screenshots (Win + Alt + Print Screen) and record on purpose (Win + Alt + R). If you use NVIDIA Instant Replay or AMD's Instant Replay instead, keep only one of them on.
Questions#
Does Game DVR reduce FPS?
Should I uninstall Xbox Game Bar?
Frametide has this setting under Tweaks, says what it does, and switches it and back with one click (some settings need Premium). With Premium it also measures FPS, 1% lows and stutters in your own game, so you see whether it helps on your PC.
