sounds like a master plan for a raster man. i have a 5850 xtreme have you heard anything performance wise from that? also i read to just allow the game to scan the hardware installed as the engine is designed to run at 60fps and the scan sorts everything out to make that so( i think thats why we have no options for graphics etc)
Also on my case the back says this game is enhanced for DirectX10 which is weird cos i thought this game was created with openGL in mind
It doesn't, the engine so far seems to fail at setting things properly, sometimes it thinks you have 0mb video memory, so it chooses all the lowest resolution textures. That's what the cfg fix is for.
OpenGL is a graphics library, DirectX handles a lot of other things (sounds probably, controls, other stuff).
The config settings are custom flags you set to force certain things like what textures to load, whether to use mouse acceleration, anisotropy, etc. I think there's a sticky thread about it.
