wined3d profiling

Hey there,

I'm experiencing some performance problems with wined3d. The affected 
game is FEAR (demo does the trick). At first I thought it was related to 
running the demo on my Intel i965, but I got the same problem running 
the demo on my Radeon HD4750 at r600g.

If anyone wants to test this himself:
Performance collapses (kinda SW rendering level) after exiting the first 
underground section. My guess is that the water plane rendering is 
causing the issue.

So anyway, I wanted to profile this one, but gprof doesn't seem to work 
so well with wine. I tried to only compile wined3d with -pg, but this 
doesn't seem to have any effect. At least I don't get any gmon.out after 
the process exits.

What is the recommended way of profiling wine components? oprofile?
