Have you tested my command stream patches I've sent to wine-devel a while ago? Did they fix the problem?
The Nvidia driver has some problems with handling single-precision float values accurately when the FPU is set to single precision mode. D3D (Wine and on Windows) sets this FPU mode by default. The command stream work works around that issue by moving GL calls to a separate thread that does not have the non-standard FPU setup.
The problem is still present in wine-1.7.13-118-g0eb6265. I tried your CS patches applied on Wine 1.7.1, and the problem is present with your patches as well.
