Damn, the PC version seems optimized as heck. Looks light years better than PS3. I put everything at max, even 1920x1080, and I haven't seen it go under 25fps. That might seem low to you, but its fine for me. I even did a FATE without any issue, though I don't think to many people were around. One thing that bothers me, after an hour of playing my video card fan sounds like a rocket taking off, its going on 3 years old though. I checked the temp while running the game an it says 90c! Oh well, its time for it to die anyway.
Didn't affect gameplay at all though.
PC version is great. It's really hard for me to hop on the ps3 version since I've put so much time into the PC. framerate, sound, and music all suffer a lot. PS4 version cannot come soon enough.
