As I said, I don't see this issue. Graphics hardware/drivers perhaps? COH has some pretty stiff requirements for the best visuals. This was pic was taken from a machine with a GTX 285 with a gig of memory running the latest NVIDIA beta drivers (190.32). Maybe COH patch revision is different on Steam. Have you installed DirectX normally? I mean, without winetricks, Steam is always installing and reinstalling DirectX. That might account for the difference.
Dollars to donuts, its hardware related. What graphics card are you running?
