Odd…
I have an Intel 5930k cooled with a custom XSPC full liquid loop running a 360mm X 80mm radiator (so heat is not an issue). I have 16GB of PC19200 DDR4 and 3x GTX 970’s in SLI (all up to date)
I barely get 30fps on all settings. When I switch some things; it’ll go to 100+FPS on High and drop right down to frame cap at 30 within seconds. I have no frame cap enabled and I really can’t figure it out.
