There is HowTo on WineHQ AppDB which says how to make this game run near perfect with no flickering textures and working cut scenes. But it is impossible to apply by normal user as it needs two source hacks/fixes.
Please consider applying that fixes in new version of CXG.
The following is copied from maaddog's test result and seems to solve most display problems:
With the below fixes & patches, I am able to run the game in 1920x1200 fullscreen, very high graphic effects, high textures but no AA if you want the frame buffer effects enabled.
To fix the movie issue (from no display to at least something) i applied this patch:
bugs.winehq.org/show_bug.cgi?id=20469
To fix the black texture issue during gameplay, I applied this patch:
bugs2.winehq.org/attachment.cgi?id=22894
I am running nvidia 190.42, Kubuntu 9.10 64bit. GTX 260 XFX SuperClocked, ASUS P55, Core i7
