Game is running pretty great for me, but I'm in this for the singleplayer, so I really have no input about how the multi is yet. Running all max settings bar the AA which I have set at TXAA x 2 or TXAA low, whatever they've called it for this game. 60fps outside of big explosion/horror moments where the frames do plunge to about 50fps, but they jump back up quick enough.
I actually think the game looks quite nice compared to some of the shots I saw leading up to release. There definitely are a few laughable textures every now and again that makes me think "Sure you might be supporting 4K, but why would you want to look at that detail-less texture in crystal clear 4k?", but on the whole it looks nice enough. I'm getting some stutter on the level loading/cutscenes once the loading bar is good, which is pretty annoying, but everything in game is good. I did encounter a brief bug when sliding was tutorialised where my controller was turning off if I slid too long, but it went away after that so I have no idea if that was something on my end or the game's end.
I will say, kind of put out the physx Nvidia bigged up is not here at launch. I doubt I'll be playing again to see them so would have been nice.
