Regarding the slight bit of rant, dont PC gamers of that flavour playing PC-intensitive games of that sort usually have dedicated modern vid cards? Or am I just dreaming here...
(not ones capable of fully utilizing Unreal3 engine of course, but you know, good enough for modern games at good detail)
I think that's the demographic they get, but not the one's they want to target. (thus the whining) They want EVERYONE to be able to run their software because it obviously affects their bottom line if only the elite few with money to burn on hardware AND their software are the only ones that buy (and don't return) Unreal 3.
