one thing that might help, especially if you can’t or won’t deinstall the KB5001330 update and having fps drop issues is to set your pc energy settings to ultra, though normaly this option is not even there, you can enable it via a cmd command, open the console and just copy paste “powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61” and press enter.
after that type in the win-search “energy” go to energy plan selection and choose the new “ultimate performance” (or corresponding name depending of your OS language)
