In the PhysX panel? My 8800GTS either, I think its because they dont have a PhysX-chip, as I understand it the older cards just emulate the effects.

I thought all chips in or newer than the 8000 series had it

I thought only the uh...9600...hmm I dont know then, anyway, the point is, mine doesnt show up in the panel either but it works ingame- doesnt yours?

Ooh I haven't tried that yet

Its the 9800 GTX+ that has the onboard phyx chip i remember pilsy telling me about it

AFAIK its live on all G92 or newer cores and emulated on anything earlier than that.

Therefore 8800GS / 8800GT / 8800GTS 512mb / 8800GTX use hardware physx and all other 8 series cards emulate it on your cpu. I think. Nvidia are being rather cagey about the implementation and keeping a lot under NDA.

Either way its all a bit of a crock. remember that by enabling physx you are using a percentage of your gpu for physics calculations instead of graphics processing. If your pc is processor limited this is just wasted gpu power you are using, but if you are graphics limited it will make your problems worse.

Of course the difference between 100fps and 200fps is open to debate, but at high resolutions you may find the need to reduce res with physx enabled.

Ha, someone did his homework.

I'm gonna go back to the old drivers for now, crashed my TF2 only once so far, that's not it, but there are only 3 maps in UT3 utilizing PhysX and I dont play any other PhysX games, not worth crashing every other time I play it.

Hehe i new pilsy would coem and post now

I just like seeing my avatar

cant decide to enable or not.

only game I could see it making mega-huge improvements to is Crysis and the like,,, if it's even supported.

I remember watching a cellfactor (or whatever it was called) demo online and that loooked kinda pretty with stuff flying about. But I'll keep my gpu power I think (unless there is a chip on the GTX)
