Yes, I know this game is old. But I've always enjoyed playing it and never had any performance issues until recently. It seems like since I purchased my new MSI 1070 Gaming X 8G it's developed constant stutters, especially when moving and rotating the camera. There will be times where I'm running, and find myself almost completely turned around. I've messed with all the graphics settings both in game and Nivida Control Panel. Processor is an i7 4790K with 32gb ram if that helps any. I've tried setting cpu priority to high with this game, changing afinity settings, reverted to old graphics drivers, and still the same result. I never get any fps dips according to both steam in game fps counter and msi after burner. I'm playing on an ASUS 248VQE at 144hz. This is the only game I have issues with like this. It was absolutely perfect with my 970. I'm not sure how an upgrade could cause issues like this but yeah, this is where I'm at, if ANYBODY has suggestions please feel free to comment.
