The new City of Villains patch is out, so AnanadTech revisits Ageia’s PPU and the effect it has on playability.  To make things easier to compare CoV now supports software physics, so the performance difference the PPU makes can realy be highlighted.
“The last time we took a look at physics performance under City of Villains utilizing a PhysX card, the code was still in beta, and the results for the PhysX card were lackluster at best. What we found was that while utilizing a PhysX card did indeed enable CoV to generate a good deal of extra eye-candy, the cost came at an immense performance drop, especially to minimum framerates. At the time, AGEIA had promised that performance under CoV would improve between then and when the improvements were actually put into the Issue 7 patch. That patch has since shipped, and we are back to take a look at just what the PhysX card is capable of doing given more refined code”
