Question GPU usage drops

[MikeC24]

Hello everyone , my GPU drops its usage quite often and causes fps drops wich increases frame times and makes the game not feel smooth at all , i noticed that when it drops usage my cpu usage spikes up for a moment and voltage limit goes down and no load limit goes up , anyone know why this is happening?
i will post my afterburners graph so you can see what im talking about , also i will list my rig down bellow , Thank you .

do you know what kind of monitor you have? with your gear you should not be having issues at 1080p. in game GRAPHICS settings make sure your render resolution is 100% and that your monitor refresh rate and resolution match that of the current monitor you are running, whether it be 60hz@1080p or 144hz@1440p for example...

also when you built the system was a clean install of win 10 performed and have you tried it recently?

Thank you fo replying , my Display is a MSI Optix Mag27c 144hz
I updated nvidia driver today and everything got worse , before it was only my gpu usage buging me and some frametime issues , but had consistent 141/140 fps and now I get like 90 fps not even in multiplayer , I tried going back to my older driver and its still the same , my cpu usage stays at 70 % and before was like 40 %
