i have an ati card at the moment and didn't need a driver at all. physx worked. i also don't have any games that use physx installed.

but i also find the reported driver problems worrying. so with a nvidia card you always need a driver? the driver isn't included with the graphics driver?

i hate installers. i don't want to deliver my projects with an installer. i think the whole physx driver requirement is very unprofessional and totally unnecessary. they should simply always use the cpu if no cuda hardware is available.
