some of nvidia vidoe cards can do hdim audio some cant. i would post the video card that you have now. the audio driver is only used if you have a htpc media box. if your playing games on a pc your onboard audio drivers take care of the sound. edit also the audio drivers wont intstall unless there newer then the ones on your hard drive.
Well the problem with the audio driver is fixed, now the ''PhysX driver'' will not install.
Will this take away the fps in games?
And how can I fix this?
