I forgot about PhysX

[Nate Silvers]

Done it 3 times. Basically Nvidia are to blame because I can't start the two games I bought the new ATI card for in the first place because of stupid Physx drivers not installing/uninstalling.

You need to google for forcing off the drivers, it should be as simple as uninstalling them but for some reason in your case it isnt

There is a fix, if a reboot doesnt help, first check you are shot of all nvidia drivers, then go into the metro folder, and in the install file uninstall and reinstall physx there should be a file to do it.

I used a GTS 220 with HD4850 for PhysX. It worked but introduced sound glitches and system instability, which I put down to having to move the hotter Radeon next to my soundcard (the nvidia card was not recognised at all if installed in 2nd PCI-E slot).

If I bother with physx again it will be just with the one nvidia card.

yes ATI is not to blame here at all.

The old Nvidia drivers are hurting your new AMD ones

Well after a painful experience with hdderase and my SSD I finnally formatted and everything it working again. I can now play Gothic 4 full 1080P @40-65 FPS and Metro is running smooth 50FPS average max.

The 9800GTX crippled at 10 fps with Metro on full and 25fps Gothic 4 720p. I would have expected a bit more of a performance boost from the 5870 though? Seems like it won't last that long before an upgrade.
