I've switch to oss driver to test how it works now with games in wine. I've read that some people succeeded in running wine correctly.
I'm running debian x86_64 testing/unstable with mesa 7.11. I use playonlinux to manage wine versions.
When I simply run an application through playonlinux, with debugging info from wine, I can see it does not find the 32 bits version of libGL.
Setting LIBGL_DRIVERS_PATH=/usr/lib32/dri fix the problem, but it seems that these files are obsoletes (wine debug info says they are from mesa 7.7 !! )
Is that a debian packaging bug ? or what did I missed ?
That's not a driver / mesa problem, but a problem with packaging or installation. To get meaningful results, you need to keep your 32 bit mesa installation up to date, too. I can't tell you how to do that on debian, though.
I've found that a surprising amount of games is working with radeon G3D + wine, but there are still some annoying rendering problems in some of my favourite games.
I'm having this same issue, and I am currently working to find a solution.
The issue has to do with the change to multiarch. Instead of relying on the ia32-libs package as we have in the past, we now need to install the i386 version of the packages that we want. This appears to be a much cleaner solution, but there is obvious breakage. The wine packages are going to need to be changed to rely on multiarch instead of ia32-libs, as it sounds like the package is about to disappear.
