Yes, VirtualGL intercepts the OpenGL commands, sends them to the nvidia card,
and sends the rendered output to the intel chipset for display.

It definitely is related to timing: I just managed to run CoD4 exactly once out
of ten attempts with the latest wine-1.3.35. And both CoD8 and CoD4 always
crash just after the splash screen when the game is trying to initialize its
graphics screen, so it sounds plausible that two active GL contexts might be
causing the crash.

What is the best debug channel to enable to see what might be going on here?
And is there an easy way to delay the initialization of GL (since I can't
revert that single commit)?
