anyone that has tried Garry's Mod VR, how was it? what maps worked? does every map/project in Gmod work with VR?

if so that alone would make me want to get a VR headset, i looked around Gmod maps and found a huge single player gang war/adventure map and that is something i would want to play in VR, something other than GTA https://www.youtube.com/watch?v=I5WgcILk07U

I also want to play through HL2 VR with the HL2 Cinematic mod
