why does it seem like my dedicated PhysX card isn't really doing anything no it dosn't just seem like it's not doing anything there is no read coming out in nVidia system monitor either with dedicated PhysX being rendered on my 9800 GT and multi-gpu mode on my GTX 295? I should have a blazing fast system with this PhysX card, I don't expect every frame to be perfect because my HDD, and maybe my RAM is probably slowing it down a little bit but I just want to see my awsome dedicated PhysX card working, it would be so awsome.
Physx is only a gimmick.
I have a Ageia Card. Bought it for 17 Eurobucks. It is worthless. The few games that use it, doesn't show any big improvment. MIrrors Edge was the only one, but flags and debris were just not enough to have something drawing 30 watts in my already cramped case.
Second, it generates a lot of heat.
Third, i have my computer on the living room. It is too noisy for my Mrs.
I went 4850 CF. If you got Nvidia cards, drop the Ageia card. It is useless. You won't notice it much, it is far from ground braking. Havoc is here (Wolfenstein comes to mind), and it is more CPU bound than anything else. PhysX was a good idea, badly implemented.
It doesn't seems your card is doing nothing, is probably doing nothing really.
