No your right, not sure when I or why I opted out of it. Will have to have a look at it. For now I am enjoying the game quite much, I can still get some graphic lag, decreasing in graphic (turns more blocky and ugly) and if leaving the session the hud will stay visible above the menues. This is happening after I have been playing for a longer period of time, shutting game, SteamVR and Mixed Reality software down usually solves that issue as neither CPU or GPU seems to get anywhere hot.
Since this last SteamVR update I have had in a total of only three crashes, one at boot of game and two game freezes. So in all itäs very good progress from my point of view
