I use Oculus Tray tool I also still let it use Steam VR rather than OpenVR but I have the SS setting in Steam set to 1.0 but in the Tray Tool set it to 1.5.
I would also recommend using the following extract it to the desktop then find( C:\Program Files\Oculus) and rename your Oculus folder (Oculus Big) then drop this folder into your program files if you want to switch back rename this Oculus Small and switch the other folder back to just Oculus.
This made a massive diffrence for me after the updates to Oculus a few months back it was a stuttering mess for me at points till I found the Small solution.
