When i boot the game my fps is normal (benchmark 191 average fps with 90/90 gpu and cpu usage). But after the first game or benchmark my fps drops to below 100 most of the time causing stutters and when I do benchmarks its around 140 average fps with 100% CPU Usage. but every time I swap my Vsync in my settings from Off to Frame 2 or 1 it will go back to normal sometimes and other times I have to restart my game.
I don't know what causes this issue iv seen no one else with this issue either.
