wine users - Sep 2010 - xsyon game, black textures? black flickering

Hi, 

the last day i tried getting the game xsyon to run. I was some kind of
succesfull but there is one last problem i cannot fix by myselfe.

 Some regions / textures are black and the grass in the game is flickering.
Cause i cannot describe it better i made some screenshots so you can see how it
looks. (The flickering is not visible, cause it only show up while moving)

The game is currently in closed beta so you cannot test it. I'm hoping that
this is a more general problem someone knows how to fix. Anyway, here is the
link the the main website http://www.xsyon.com/.

System Details:
CPU: Intel i7 quadcore
Gfx: Nvidia Gforce 275 GTX
Gfx driver: 256.53
RAM: 8 GB


Thx

Ah, i forgot to mention.

I had to install d3dx9 with winetricks to get the game running. Maybe that
matters.

I noticed the images posted in the first post are not working correctly so here
are links that should work:

i have run into different 3d games even linux native games in a few of my
computers, and installed driconf second tab image quality, and set it yes the
part that says Enable s3tc texture compression even if software support is not
available and that have fixed lots of gfx issues for me
