Just thought i'd share this nifty trick found by user @droseofc
while we where troubleshooting some stuff regarding Oculus Tray Tool. If you set Oculus Home to Run as Administrator, it will not automatically launch in the background when starting Steam VR games. This might save some valuable resources as well as make Steam games launch faster. This will also, however, cause Home to not start automatically when you put the Rift on your head. So there's two sides to this so to say. To set Home to start as Administrator, you right-click the Oculus shortcut -> Properties -> Compatibility and down at the bottom you check the box "Run this program as an administrator". Done!
You might need to start Oculus Home manually one time and dismiss the Health & Safety warning so you get into the lobby. After this you can close Home and start Steam VR games as usual and it should work fine with no Home starting up in the background.
So this might need to be done every time after you've restarted your PC. As i mentioned this was discovered by @droseofc
, i just tested and verified it. Hope someone finds it useful, couldn't find any existing posts about it.
