@CMM In your screenshot you’re editing the wrong file. It needs to be steamvr.vrsettings not default.vrsettings.
open cmd and run
C:\Program Files (x86)\Steam\steamapps\common\SteamVR\bin\win64\vrpathreg.exe
it will tell you what folder your current config files are in. then edit steamvr.vrsettings
if the setting isn’t in the file then add it so it looks like in the screenshot
also this was meant as a reply to the original post but it should work for @industria as well, just dont mind me talking about your screenshot
