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! Well, i tried another Unreal Engine 3 game, Batman Arkham Asylum and i have the same fps drops. Is this a bug with the UT3 engine and the new AMD cards ? I have the latest Adrenalin 18.8.2 drivers and i 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... Any more settings i can try? One of my friends have a GTX970 with the latest drivers Nvidia drivers and UT3 is running fine. BTW, anyone here with the same card? This card should be silent with the Twin Frozr cooler but it gets really loud when i'm gaming, i had to lower the max fan speed from 2400 rpm to 1700.
