Quick impression. This seems really good. 1080 Ti plus i7 4790K, running at 1440p. Running mostly at 100+ fps, I saw it drop to the low 80 in the busiest scene.
This is with everything maxed out except for AA, I had that at SMAA. That's the only real issue I had so far, SMAA leaves a lot of shimmering edges, MSAA murders framerate (it drops the framerate by about 30fps), but doesn't seem to do anything. The game looks really clean, but it could be a smoother presentation.
I'm really impressed with how it plays though, this is a revelation after playing Destiny 1 on consoles. Responsive mouse controls and high framerates make a huge difference.
