I'm goign to post this on the performance thread too, but... I'm actually doing pretty good on my end.
GTX 780ti 3770k and running at 1440p. Playing on borderless window mode no Vscyn no in game AA (using FXAA from Nvidia panel).
Everything as high as it goes (textures at normal) but only Nvidia rain and light effects.
Getting avg 55 FPS. WAS getting some awful stutter, but now only when using the batmobile. Also getting some textture pop-in, and occasionally it takes textures forever to load.
Other than that It's been pretty good, smooth, veyr little stutter (mostly when in the batmobile, so I'm avoiding batmobile missions). But I just finished playing na hour fo the game, and it's pretty good. Still nto what it should be, but I think I'm going to keep playing, at least until the game starts to force me into the batmobile more.
Tried locking to 30 FPS. Tried playing on my friend's Xbone.
Sorry, console gamers but 30 FPS is just the worst thing ever. Not willing to go from 55 even with a few stutters to 30.
So not the end of the world, but these guys need to release a patch soon.
