What is your GPU usage? (not talking of VRAM)
EVGA GTX 780 Ti SuperClocked @ 1250Mhz GPU / 7500Mhz VRAM. There is no throttling, temps are under 70C, I tried stock clocks and overclocked, but regardless of that and regardless of drivers, I can't get stable 60fps out of this game @ 4K. Its closer to about 40-50fps @ 4K... ALL OTHER GAMES have no issues running high framerate @ 4K, except for some like Crysis 3. But the point is that this game is not graphically taxing, so why is it running at only 40-50fps @ 4K?
