Hello,
Regarding this type of issue, it appears that problems have been occurring on NVIDIA and AMD systems since the January update KB5074109.
Some users have reported that after installing KB5077181, game performance decreased significantly, including major drops in frame rates. There are also multiple reports that uninstalling KB5077181 resolved the issue for them.
Although KB5077181 includes the following improvement:
“[Gaming] Fixed: This update addresses an issue that determines device eligibility for full-screen game experiences,”
some NVIDIA users are still reporting low frame rates and instability on various support forums.
Please open Settings → Windows Update and check your update history.
