That's certainly pretty recent.

I have a MacBook Pro here and I use the GeForce 9400M (it also has a 9600M GT which I don't use).  That's 
pretty much the same as yours, so you would say the hardware/driver cannot be the issue.  I also occasionally 
test stuff on an older MacBook with Intel graphics running Tiger, with good performance.

It would be interesting to know whether I can reproduce the problem on my machine here.  If so, then I can 
also look into debugging it.  Is the application available somewhere?  Or is there a stand-alone test case 
that shows the same behavior (that would be even better)?
