Hi,
Yeah, this is a total collapse of the framerate. Good catch on that Xinerama
thing. Do you have direct rendering with Xinerama, or does the driver fall back
to accelerated indirect rendering? This could explain some performance
difference with buffer transfers. Does the problem also happen when you use
Nvidia's twinview instead of Xinerama?

Either way I suspect there's a bug we hit in the driver. The best step would be
to isolate this bug in a stand-alone opengl testcase that doesn't involve Wine
and report it to Nvidia.
