Unfortunately the game doesn't seem to run all that well. Or rather, it's just kinda stupidly demanding for what you get. Being more demanding than the first game is understandable with the improvements in visuals, but the result is a bit extreme. GTX970 users are only getting about 50fps average on *Medium* settings at 1080p. You're gonna need a GTX1070 to get 1080p/60fps on High.
AMD users are faring better as it seems they hold a pretty big advantage over Nvidia, but it's still quite demanding overall.
Still excited to play it, but this will probably be the first game where my GTX970 cant do 1080p/60fps with decent settings and that's a bit lousy. There's a chance something can be done about this as GPU usage is fairly low for Nvidia users for some reason(and it's not being CPU bottlenecked, either), but for now, it's not looking promising on the performance front.
Just a heads up.
