physx source code is crappy. nvidia employees even admit it themselves:

Quote:
"It's a creaky old codebase, there's no denying it," Skolones told Ars. "That's why we're eager to improve it with 3.0."

i guess there still is a lot of ODE code in it (novodex got founded by some ODE coders). tongue ...but due to all the marketing millions everyone thinks it's the top physics engine when actually the others are much more modern.



edit: in the trampoline example in the video the physics looks a bit buggy when some of the balls rocket away with extreme speed.
