Manufacturer: Nvidia Model: GeForce GTX 1060 6 GB Operating System and version: Windows 10 Home (1809) Does the game load (and error you get if not): Yep! Driver Version: 425.31 Monitor Resolution: 1920 x 1080 Multi-monitor?: No. Graphics Preset Used: All Overall experience: The game mysteriously runs at 60 FPS in some place; 20 FPS in others - regardless of whether or not the graphics settings are at their absolute minimum or absolute max. Any steps taken to resolve issues you encountered: Mostly, research - but the only potential hook I've been able to find is that the game forces itself to run on 'Low Priority'. Attempting to set it any higher only makes it set itself back; so I've been unable to see if that might be a potential cause.
