I don\'t believe you can use pssetup(.app) at this time. As far as I know, dfryer hasn\'t finished it yet (I wasn\'t even aware that it was included in the package). If you want to change your resolution, you\'ll need to modify planeshift.cfg. I suggest you search (see link in my sig) for a thread that discusses this. As far as speed problems go, try using Adaptive Distancing to help bring up frame rates.
