I still haven't tried the 2.1 version of the Smooth patch. I'm reading conflicting information on what to edit or do with the Package files. (ld_SmoothPatch.package ; ld_SmoothPatch_MasterController.package)
I've read it's suggested if you use Nraas MasterController, Cheats and Integration to leave the package files out, so it doesn't conflict with the Nraas mods or cause problems with your game.
I was working with version 1.-something until I uninstalled it today. I was thinking of leaving it uninstalled for a little while to see if I notice any differences.
