This game has made a good case for developers never including MSAA in a game ever again. People are just too stupid.
Anyway, it runs very well for me: 60-100fps on a GTX 1080. 1400p / Ultra Settings / CHS "On" / Sharpen Off / CA Off / AO "On"
One thing I noticed is that there is a huge amount of AO shimmering when you turn off Sharpen when using AO set to Ultra. Changing AO to On resolves the issue. I think people are misdiagnosing this as TAA ghosting but it seems to be a bug with the aforementioned combination of post effects.
Mouse control sensitivity is out of control, as many have already remarked. I'm not convinced there's any actual acceleration though, just stupid high sensitivity and a weirdly inconsistent ratio of horizontal and vertical movement. Hopefully they can patch that quickly, it can't be too complicated... right?
I had my graphics driver crash once in the first 6 hours of play. I also ran into some UI soft locks when hitting ESC at the wrong time during menu transitions
The benchmark is significantly more demanding than the actual game, so don't assume your game will at the framerates reported by the benchmark.
Also, I had an issue where my card's core clock refused to go above 1GHz (it should be ~2GHz). Setting power management to Prefer Maximum Performance in the Nvidia control panel solved it.
