It's weird how gpu usage is at 99% during the initial menu screen, but during gameplay it hovers at around 40-50% usage. One core out of four is working at 60-70%, the rest are at low 20% range. 15 FPS during gameplay is not playable. I would be happy with a constant 30 FPS, but not lower. I spent over a grand on my PC to play games at 60 FPS, so I feel that this game is a huge let down.
