Maby someone can upload an A8 physics demo (a compiled exe).
So I can test that on different computers.

If it really requires a user with an older XP Machine to install the 33MB PhysX Driver, (http://www.nvidia.com/object/physx_system_software.html)
its not an option to use physics anymore for small projects.

Downloading and Installing such a big driver would be too much to demand for
running a small casual game using physics.
