Just finished chapter 3 last night and I have a few observations:

The first is that it's poorly optimized as hell. It has a severe lack of scaling options and can barely keep an FPS over 30 on my system that can nearly max Skyrim out at a steady 50-60FPS despite not looking much prettier than something like Resident Evil 5 or one of the PS3/360 generation SIlent Hill games(and that's with the resolution cranked down a little to like 1000p, I might play with a little more).

Even turning the AA off doesn't seem to do jack for the FPS, leading me to suspect it's a dummy option that doesn't even do anything because I can still see rough edges on certain models if I look close. The saving grace here is that the game is slow-enough paced is still plays fine at those lower frame-rates.

The games "suggested" brightness level is "can't shit unless I'm in a room brighter than the sun" and I had triple it in order to make the light-levels balanced enough to actually be comfortable to look at without straining and actually be able to enjoy the graphics.

I'm enjoying it other than that though and I hope they release a patch to optimize it a bit better so I can at least get a consistent 40FPS out of it.
