Hi, I'm getting a graphical glitch while playing Evolve on my retina iMac. Symptoms are a roughly rectangular patch of flickering black squares in the upper-right part of the screen. This only usually happens near the start of a game, lasts for maybe a minute and goes away. It may come back later on but usually does not. iMac specs: Retina iMac 27" 16GB RAM AMD Radeon R9 M295X Windows 7 Bootcamp Evolve graphics settings: Full Screen Resolution: 1920 x 1080 Anti-Aliasing: SMAA 1TX VSYNC: 1 Frame All Other Advanced Settings: Very High I've tried lowering the resolution, removing FSAA and VSYNC, but it still seems to occur. Is anyone else observing this behaviour? I can live with it, but I feel that I shouldn't have to. I considered changing from default Bootcamp AMD drivers to the official ones but a google search shows me that this is actually not as easy as it sounds and may cause problems with my system. But please let me know if you've had success with this. Thanks for any info.
