I noticed after about 2 hr of playing the fps seemed lower.
Using hwinfo to test I noticed the vram creeps up in usage gradually and never reduced back. After about an hour it had creeped up to about 94% usage from around 60-70%.
I think this also creeps into dram with virtual memory hitting 95% and also exhibiting the same increase in usage over time.
Quitting to menu or exiting game helps.
