Re: 560 can't do physx?
Tried re-running the installer and selected manual. physx was selected and it does seem to be installed but Eve still uses cpu. downloaded fluid marks and ran that and it will switch between cpu and gpu depending on what you select in fluid marks. So I guess the program can force the selection.
However, when using GPU it crashes after less then a minute of stability test run every time. Card does not seem to be over heating at all.
