Ok here we go:
3770K @ 4.2
Windforce 670GTX OCed 2GB
16GB RAM
WIn 8.1
1080p
Went all Ultra except post processing and Tesselation with 4x MSAA. The initial sequence played at around 35-40FPS. When I got to the second bigger section (Hinterlands? Something like that
) I saw the FPS take a massive drop to around 30, sometimes down and sometimes up. I changed the settings then, and turned off MSAA entirely, but upped post-processing to Ultra. This basically gave me a 10+FPS boost and I can't notice much difference, so I am gonna stay this way. Definitely pushes my rig to the border though, its spewing heat like dragon farts. Maybe its time to treat myself to that 970
