I have an MSI R9 390 and after installing AMD Radeon Crimson, I began getting artifacts in Fallout 4. So I reverted back to the 15.11.1 beta drivers (had no problems with them previously) and am still having artifact problems. I double checked this using 3dMark and have artifacts there as well. I have my card running at stock speeds and voltage and followed AMD's guide on uninstalling drivers. Any ideas?
