GeForce GPUs are slowing down after installing the Windows 11 2022 Update

Some users of Nvidia's GeForce graphics cards are noticing severe performance issues after installing the Windows 11 2022 Update (aka Windows 11 22H2) that Microsoft released to the public earlier this week. As reported by Bleeping Computer, affected users have experience stuttering, inconsistent framerates, and slowdowns, even on fast PCs with modern components.

Nvidia says the problem is caused by some new Windows graphics debugging features that are enabled by mistake.

The company publicly acknowledged the issue and released a new beta version of the GeForce Experience software package that it says should fix it. This implies that the problem is with Nvidia's add-on software rather than the GeForce drivers themselves; if you installed the drivers without the GeForce Experience software, you may not have noticed the slowdown in the first place.
