General questions about sys-gui

I tried to familiarize myself with sys-gui - the concept, the technical details on how to activate it and similar. I am quite aware that this feature is experimental and yet I’d like to test it. Beforehand I have two simple questions, because I am not sure if I got it right…

  1. Does the sys-gui concept improve the usage/performance of the gpu in comparison to the gpu sitting in dom0 in any way or is it just to fix the security concerns explained in the news article. I.e.will we finally be able to get hardware acceleration out of it?
  2. Is it possible to revert the changes without the risk of having residues in my system e.g. by using a salt formula like the one to enable the feature in the first place?

Thanks for your help!
