Ageia's PhysX benchmarked

AnandTech has put up a review of the Asus-built Ageia PhysX physics accelerator card. The review accompanies the release of Ghost Recon: Advanced Warfighter, and naturally AnandTech decided to test the card in this PysX-accelerated tactical first person shooter. Surprisingly, the numbers show a frame rate that's actually lower with PhysX acceleration enabled than without, and this holds true whether the test is conducted with a 1.8 GHz Opteron 144 or a 2.8 GHz Athlon 64 FX-57 processor. AnandTech attributes this to the debris in the explosion effects, which it says require "instancing all these objects on the PhysX card and then moving them back and forth over the PCI bus and eventually to the GPU." Two short videos showcasing the performance drops are supplied with the benchmarks, and the problem can also be seen in PC Perspective's high-res footage of the game posted earlier this week.
