Game will be Far Cry 6 from ubistore. Updated.

So i played game few times ( tutorial island and driving on a car ) there was no stutter at all.

Today i launched game and had fps drops for a second and gpu usage drops for a second. Drop from 130fps to 80fps and back again. The same with usage. Drop from 80% to 40% for a second and back again. Just random 1 second stutters. That was when i was driving a car. So i quit game,relaunched Ubisoft launcher played again and it was fine.

My question ,why i had that stutters? Temps are ok.

I was on 1440P
