Ok I recently bought a Phyxs card from shadow. I finally got it in and was very excited. The first thing I did was install the latest drivers from Nvidia. What happen? They wouldn't recognize the card. I then contacted Shadow who informed me I had to download the original 7 series driver first and then update to the latest. I had to go with the 8 series but they worked fine. Once I downgraded the driver my system saw the card fine. UT3 never looked better. Warmonger was a cool novelty and I was really digging this whole Physx thing. Thats until I updated again. Once I updated the drivers to Nvidias latest my card was still recognized. The only difference was it gave me the option to use the Agiea card or a Geforce card. So I select the Agiea card and be about my way thinking I now have the latest of everything. Go me! Once I started UT3 again I noticed my performance had dropped a LOT. Not as bad as having no Physx card but not what it was before I "upgraded" the drivers. The Tornado level became down right unplayable. So I checked my CPU usage. I was surprised to see it running at 95 - 100%! How could this be when I had a dedicated PPU? Then it hit me. What if Nvidias new drivers do not dedicate all the physx to a second GPU as Nvidia advertises and off loads some of the work load to the CPU. Here you are thinking you have a "dedicated" GPU for physx and your really just using 50% of it. Makes me think Nvidia is up to shady marketing. If I'm wrong about this please school me. I'm just looking at what I've see first hand and now tossing the question to the forum. What do you think? Is Nvidia up to no good or am I having a noob moment.
