driver problem.

hi,
my intro http://87.230.1.191/nuke/temp/Roboman.zip

gfx5500 first driver very slow run.
But new driver normal runing.

why?

you answered your own question, the driver

but why?

problem my code or not my code?

You probably used something that had an early unoptimized driver support, like VBO had for a while, the newer driver fixed that, so now it works like it should.
