I've got an HD5770 1GB Mac edition and I'm running into a frustrating issue. The drivers were automatically installed by Windows, but when I try to play Assetto Corsa, the core clock gets locked to 398MHz. I've switched off ULPS (0) but still no luck. I've tried using DDU to uninstall and reinstall drivers multiple times, but I keep encountering errors. Interestingly, other games run fine, and I can even achieve 1080p 60fps on games like ETS 2 and Lost Light, but Assetto Corsa is a different story. I bought this card as an upgrade from my GT630, hoping to reach at least 60fps, but I'm stuck with 15-30fps!

What version of Windows are you running? Just so you know, the HD5770 is quite old, and driver support for it stopped back in 2016. It might not be powerful enough for certain games now. You may need to consider getting a newer GPU to avoid these issues.
I'm on Windows 10, version 22H2. It’s a bummer because I can run GTA V and ETS 2 just fine! I really hope I can find a fix for Assetto Corsa.
