Uninstall OLD version
Install New version
our fellow reader Stefan has provided us today with a link to a new PhysX System Software 9.11.0621, that he has extracted from DELL OEM drivers.
We have not found anything particular new (updated PhysX .dlls, for example ) in this release and since this driver is not fully offical – we recommend to install and/or use it at your own risk.
