profiling

[NaN]

Oh, I forgot to mention. The data is from the bullet branch. But it shouldn't matter as I didn't modify the scenegraph code.

I am testing it on a Windows 7 x64 machine(Athlon 64 X2). The VC9 build is compiled with /Ox. It is in fact about 20-30% slower than the GCC4.4.3 -O3 build.

Here the GCC build profile:

Funny huh? Will profile vdrift trunk asap.

About the texture stuff ...

Yeah, I think it's just me not trusting the OpenGL drivers on Windows. :lol:
