I use it. Wish it ran better and seeing as I have a nice enough video card to run GTA4 at full graphics I dont understand why it doesnt :/ but I still think its going to be lovely when its done.
I use it, It's pretty nice for me. (I'm a cheap bastard who dosn't want to spend my money for a new graphic card.) And becuase you that I don't have shaders. And it does run a bit slow for me.
