Can you show us which commit fixed it (by running a regression test)?
Shall I compile and test every commit? I think it would be easier if you try to upgrade your NVIDIA driver first.
Fedora 16 still has 290.10 for a reason. Alternatively, you can run Guild Wars with previous Wine versions to see if the problem exists for you now that the driver has been updated.
