Hello guys,
I have a problem with my graphic card amd r9 380 4g: when I work with my landscape the driver crash. I have the last driver version but I also tried to use the 15.11.1 beta and I have the same problem.
Anyone had the same problem and can help me? Thanks 
It looks like you tried the stuff in this thread: Amd Driver Crash? - Community & Industry Discussion - Unreal Engine Forums with the driver 15.11.1… When you installed it, did you run the tool that completely erases your driver (from safe mode) and then re-install? Display Driver Uninstaller Download version 18.0.5.0
I had the exact same card as you and as an AMD fan, I had to ditch for a 970 because I couldn’t take the crashes… Good luck.
