Slow particles with 9800GX2


I’m using the CUDA particles demo as a base for my work.
Recently I discovered that it runs 10 frames slower on 9800GX2 than on my old 8600GT. I try the 1.1 and 2.0 version of CUDA, the result is the same. I didn’t try all the other SDK examples but they seems to run faster on 9800GX2.

Do this demo has scalability issues?

What drivers are you using?

I use 175.19 drivers.
