A fair few reviews mention negatively that the game runs poorly on maximum settings (read in suit voice) even on high-end PCs.
I can't see why that's a negative point at all. The game looks fucking fantastic on high settings, pretty great on medium and damn passable on low settings which caters to just about any recent system. The fact that it is also future-proofed for upcoming hardware advances with a ridiculous ultra setting is a solution to what PC gamers* have been whining about for years - current-gen consoles holding back graphical advances in our poorly ported games. Well here's what happens when a dev makes a game suited for a PC with properly scalable graphics for tomorrow's hardware. It's awesome.
