Just a funny fact that I found...
After opening several tabs for looking for the Nvidia specs, I left them
open. I am using FireFox.
I hit play again and the fps dropped by half 24 fps.
Start scratching my head. Closed the addtional tabs of Firefox, restarted
Softimage and the speed was back to 50.7
So my guess is that this modern browser suck a lot from the GPU... pfff.
