fps spikes

I need help with my game, i have recently seen that whenever i hover over something or do anything with my mouse or do anything ingame like moving or even standing still i get fps spikes. my fps will be around 160-200 fps and then for a second drop to 40 and then back up and it happens i would say every 4 seconds im playing the game. its annoying with these spikes as im used to the smoothness. the problem only occurs on this game all the other games i have tried and nothing happening on the other games. i got an i7 and rtx3080 n i have put wow on priority for my cpu usage whenever im playing the game. if anybody could help it would be amazing it has been like this for me for like 2 days.

Menu > video > disable "hardware cursor"

Got them too, didn't get them 3 days ago. Sunday was fine, tuesday was like that. I'll try the solution here but I think it could be driver updated, I think it happened sunday night or monday
