Hello all, i got a MSI RX570 4GB to replace my old HD6950 2GB and i did a Windows 10 Pro 1803 clean install. Games like Far Cry 3, Serious Sam 3 Fusion 2017 (beta) on Linux and Quake Champios on Steam are running great with high settings. But i still play old games like Unreal Tournament 3 with friends and to my surprise i have stutter and frame drops with this 11y old game on heavy action! (Sometimes around 30fps, or under). I tried with Vsync on and off, framerate smoothing on and off, no positive results! I tried another Unreal Engine 3 game, Batman Arkham Asylum and i have the same fps drops. I have the latest Adrenalin 18.8.2 drivers and also tried the Crimson 17.11.4 but i got the same frame drops. I know that Unreal Engines are Nvidia optimized but my 7 years old HD6950 could run these games with max settings with no frame drops (Other non UE3 DX9 games like COD 4 Modern Warfare are running fine). Is this a bug with the UT3 engine and the new AMD drivers?
