I am slowly despairing. I own a Radeon RX 6800XT and a Ryzen 7 5800X. Motherboard is an ASUS ROG Strix B550-F. It all runs on Windows 11.
I have the problem that e.g. with a certain game (Tomb Raider Custom Levels), the frame rate drops to 12 FPS. The engine itself only manages 30 (Tomb Raider 4 Engine from 1999). But with FPS 12 the whole thing is of course unplayable.
Of course I set my RAM (Corsair Vengeance 32 GB 3600MHz) correctly in the bios. I have already visited a few pages in Google and tried many tips. The whole problem came up recently, nothing was changed or the same.
Does anyone happen to have an idea where to start to narrow down the problem? I completely reinstalled Windows today.
Thank you in advance and have a nice Sunday.
