:slap: for me - you're right. I'd been swapping gfx drivers and forgot to reset to 75Hz. So now it runs at 75 fps and I imagine that if I take the PhysX card out, it will also run at 75 fps.
I suppose that had CellFactor been unable to run without the PhysX card installed, I would have been impressed. Well, it does and I'm not.
Neither can I fathom what sort of tests these cards were given at the pre-production stage or even the pre-sales stage. Is anyone else getting this to work with SLI (as recommended by one of the Ageia people) because plainly it's either not utilising mine or the bottleneck is elsewhere? Or is this just a CellFactor problem?
Anyway, it has a nice blue LED, so mustn't grumble eh.
