First off I can run the game perfectly fine at medium settings, so please don't take this as a complaint.
That being said, the only reason I don't push the settings even higher (it'd be nice to activate the special effects) is because I risk framerates of 50-55 fps. I typically couldn't care less if I were getting 55, 60, or even 40, but 2k15 feels unbelievably jerky when it's running at anything other than a constant 60. I shouldn't be able to blatantly tell when the fps has dropped from 60 to 59 or 58, but I can.
Is this a known issue with the game, or do I need to make adjustments in the Nvidia control panel?
