Do you happen to have a separate Physx card installed with older drivers? Maybe 7970/CF has issues without official driver.....
I'm running latest Cats and had no problem playing it with my card, and have software Physx driver 9.10.0514 if that helps.
My system is fresh install with the 11.2 drivers & cap3.
No other physx or nvidia drivers at all. Do I need to install physx drivers separately ?
I thought that was only for nvidia gpu's. I'll give it a go anyway. Didn't realize there was a separate set of drivers required, well, Me2 didn't (unless it installed in the background ). Oh well.
Installed the PhysX software and got it working. The demo still seems flaky to me. "Alt tab" seems to crash it for me. Me thinks new drivers are in order...ahem ahem AMD? = )
Does the Nvidia PhysX software actually pass off the calculations to the CPU if it cant detect an Nvidia GPU? or is it just so the game can detect a file, whether it uses it or not.
It does, but it only uses one core I believe to do the work of a would be Nvidia card.
Many games use PhysX but it seems only a handful support it in hardware, here's a list http://physxinfo.com/index.php?p=gam&f=all
The ones with the star have hardware support ie using a Nvidia card in place of the cpu.
Many rightfully rag on it because it could most likely be fully accelerated by modern cpu's if it was programmed to do so.
I didn't get this error (or any error) when playing through the demo with my system in sig. I'll have to go back and see if PhysX is installed.
