Severe lag problems on kernel linux515

I seem to have severe lag problems on kernel linux515 (5.15.86-1).
I use the official nvidia driver 525.78.01.

With lag problems I mean that I can barely move my mouse pointer and other responses are also veery slow.

Kernel linux60 is working normal.
Same nvidia driver version.

I could try to get more debug info, but I don’t have the time right now.

I know the kernel update was already in the update from 4th of January, but I can’t add a comment there, because it’s closed.
