weapon model issues

Hey there,

I just tested FEAR with updated software components and it looks perfect, apart from a minor issue that only seems to affect the weapon model.

Screenshot is attached and as one can see, the weapon model seems to suffer from z-buffer issues -- to me it looks like the wrong depth compare function is used.

Isn't that just http://bugs.winehq.org/show_bug.cgi?id=27145 you're seeing?
Comment 2 Tobias Jakobi 2011-07-31 06:28:35 UTC
Hmm, I wonder why it works on my Intel Ironlake then?
Thanks Henri, going to further check if I'm actually seeing this wine bug.
Comment 3 Tobias Jakobi 2011-07-31 06:39:59 UTC
Yeah, Henri was right. I just didn't see it because the game is a lot darker on my Intel and I also have lots of these blueish artifacts from bug #38357 on screen, especially where a lot of polygon edges are.

Made it quite hard to see that the weapon is indeed also translucent on the Intel.
