Still looks the same, both the game and the output from wine.
I was about to give up with this game but then I decided I would find the single-player demo so that I could report some bugs to WINEHQ and see if they could do anything with the game.
I found the single-player demo here http://www.chip.de/downloads/Men-of-Valor-Singleplayer-Demo_13014873.html
and I installed it. The demo then proceeded to install Direct X 9.0c. The demo didn't work BUT the GOG version of the game started working, the only thing you won't see is the "2015" logo being played but you'll hear the sounds and all.
I am currently emulating a virtual desktop for the game as I am trying various things out to see how it will run in different conditions and so far the game looks OK (see the attached screenshot does mine look the same as yours?).
I wish I knew which winetrick corresponds to the version of Direct X 9.0c installed by the demo, perhaps someone who is much smarter than me about these kind of things can figure it out and we can all avoid installing an unnecessary demo :)
The main problem will be the .BIK movies that the game uses :/ You can rename the intro .BIK movies to skip them but if you want to watch the others then you'll need to install a .BIK movie player for Linux and watch them that way :)
My game appears to look the same when I set UseGLSL to disabled (clean install in clean prefix, no native overrides/winetricks/demo version installed). If I don't disabel UseGLSL, the guy in the front would be black. Probably the car too.
If someone's got something helpful to add, I created a bug report on wine..
However it looks like an unimplemented feature. Unfortunately I don't have the time to get my hands dirty, and I can't really expect anybody else to code it for me...
