I have never gone below 30fps with everything cranked up on 1920x1080 (Single 5870).... the fans have to grind a little harder but its not the end of the world really.... We complain (myself included) but honestly, I don't go more than a year or two on any one piece of hardware anyway..... So shorter lifespans really don't bother me as much
I would think they'd get the engine straight soon though...
Crystal tools is fairly new and has only been used on Xbox 360 DX9 and PS3 OpenGL compatible hardware...
Never on a PC and never DX10 or above... so its going through a few Growing Pains....
Right now it's at that awkward Ben Seaver Stage where its voice is cracking and its not a cute little kid anymore...
I think it can be fixed though... Instead of having to cast Leonardo DiCaprio on the show
You see what I did there?
