Before I get accused of trolling by some fanatics in this community I better post my specs that won't help anyway in my opinion.
AMD FX-9590, 16GB RAM, R290 4 GB, W10 and the 15.11.1 Beta drivers. Ultra settings in the game.
The problem seems to occur on the current stable and Beta drivers.
Only switching to the lowest settings helps. The issue occurs to all AMD graphics card owners according to the EA forum.
I am getting that exact same issue
Intel i7 3930k, 16GB RAM, 2x R9 290 (crossfire enabled), Windows 10, 15.11.1 Beta Drivers
Have not tried switching to the lowest but why should I? I didn't fork out 2 graphics cards just to play on low; could've saved my self the money and bought a 750 ti lol.
Same problem only on caves map.
Ultra Settings. Pb desappear when lights settings set to medium instead oj ultra.
i7 4790, 32Gb Ram, Asus R9 290X DC2 OC, Windows 10 Pro 64, Last drivers (radeon-crimson-15.11-win10-64bit.exe)
