So after watching a lot of people play this game, I've noticed many, if not, all of them, have a custom portal gun skin and some people have like custom cubes, elevators, walls, ect... I checked the steam community workshop to see if it was there, but all I am seeing is Portal 2. How do I get custom skins?

Does anyone know the settings to use to make livestreaming Portal run smooth? I was testing a bunch of settings, but they were all so laggy for the stream. My resolution is 1366x768 and I am playing on a laptop if that helps with anything.

So I know the vast majority of people who speed run are on PC, but at the moment I am on Xbox. Does anybody know how much time to take out or take in when there is loads? Like, at the moment, if verified, my best run is 28:44 WITH loads. What would it be without loads? Like does somebody already have the numbers for me? And if I ever switch over to PC, what is the time removal there also?
