Stefan, it appears your assertion is correct about this being an NVidia bug. I
downloaded the Unigine heaven benchmark (2.5 basic edition) and ran that in its
default settings (windowed 1024x768). With xinerama I hardly hit 20 FPS, using
separate X screens, I had about 45 FPS on the same areas (peaking to a bit over
70 is some parts). (Of course I used the Linux version)

Could you (or anyone else) write a simple test case I can run and submit to
NVidia, as I have no experience whatsoever writing things like that?

As I still think this is partly a regression in Wine (the game worked perfectly
before), would it be feasible to isolate this case and restore the old wine
behavior just for this case? Or should I just keep a revert of that commit in
my git tree until the issue is properly fixed? I imagine others may be hitting
it as well.

However I don't see how that same issue is affecting Joel (comment #11) as he
doesn't use a dual monitor setup, so I doubt he will be using xinerama, or
perhaps xinerama only worsens the case (a lot)?
