Man optimization doesn't seem that good.
I first loaded into the game with highish settings. Played a bit but the FPS was around 30fps which wasn't good, backed out and changed the settings, dropped AA off for one. Started the game again, and still only had around 35FPS. Barely changed anything.
At this point I decided to just run through the intro so I didn't have to keep seeing it over and over again while I tweaked settings. Which by the way, it played really awfully at around 35fps, controls felt really sluggish since it seemed to cause some input lag.
I've been messing with the graphical settings again now I'm down onto the world and even if I turn everything off, I'm still only getting 40-45fps at 1440p. Most of the settings don't seem to improve the frame-rate much at all.
I get that a 970GTX isn't that good anymore, but man, it's not like the game looks that amazing anyway. Really disappointing.
(This is using the Borderless Gaming app, by the way, I'm not sure if that's affecting performance any)
