Well, to be fair, I'm running hardware that's almost 4 years old now.
CPU: Intel Q9650
GPU: GeForce GTX 295
6GB DDR2 RAM
The problem is, I'm well above the minimum specs and only fall short of the recommended ones in VRAM, and not by much. My PC is still more powerful than current consoles, so there's no excuse for such shitty performance.
That being said, your card is more recent, so you shouldn't have any problems. But I have heard reports of people suffering from performance issues on high-end hardware too, so who knows. The engine is an unoptimized piece of crap, basically.
Yeah, I've been hearing the game scales wonderfully. Good on IG for making a great port.
