I have recently been having several issues, possibly related to update? I never had these issues before. I have noticed brief, but frequent, gamma fluctuations, ground textures appearing in the water (usually in periphery), frequent FPS drops (that seem to happen more on MP) in a cyclical pattern. On SP i will get 90-110 fps. When the FPS drops happen, i'll peak around 80 and it drops slowly down to 15-20 fps, then jumps back up to 80 and drops again. I have troubleshot several things and haven't noticed any changes in other games. GPU passes stress tests. Tried a different monitor, same thing. I never had these issues in DCS a month ago
Best,
Nate
EDIT: Ground textures appearing in water (spontaneous/brief artifacts) seem to have disappeared when rolling back to 2.5.5. Unclear if FPS problems will persist but not likely, as they were not an issue in the past. This may have been the issue, found no problems after hours of hardware and software troubleshooting.
