Ha I tried a bunch of stuff (there was a biggish SteamVR update, new angles on lighthouses, turned off a bunch of software) and had a few solid hours last where I noticed almost zero tracking skips, tried out a bunch of stuff and really enjoyed it, then closed SteamVR for a bit, came back after dinner it was back happening almost constantly. I just don't get it!
Gonna try a complete full install of everything and set up for scratch tonight I think. Every time I think I've got it maybe sorted and can live with it, it returns with a vengeance.
I realized the easiest way I might get anyone to understand exactly what issue I'm talking about- it is really, really, really noticeable and reproducible when anything is
loading. If nobody else has experienced that, then I am very far off from the performance level others are experiencing. It's super noticeable like for example when The Lab loading screen is up. I'll look at the image and it will be stable if I'm not moving my head, and then if I do it skips around a ton. Once it actually loads (actually, a few seconds before it finishes loading), the effect is lessened substantially.
