This patch which you can download here.
Addresses a huge problem we been having with the PhysX system in Neo Axis. This fixes all the Gitteryness with the physX system and it has been updated to PhysX 3.3.4.
I would like the Thank Ivan, Incin, and Firefly for fixing this problem and getting the engine physX system updated.
Also this will be the last patch for this month. And should very much fix all problems related with the PhysX system.
