I had exactly the same issue after upgrading to Windows 10 2004. I downgraded back to 1909 and the issue went away.

No you effectively did a system restore, it just so happened to coincide with the last vive update, I'm on 1909 and have the same issues.

Any chance you have done an nvidia update or used the GeForce Experience to automatically optimize your game?

 

I considered the same thing, the following steps have so far helped to improve things;

Disable all overlays
Run Steam as admin (This is super important and never really said anywhere in the setup, but old threads show that SteamVR doesn't work so great without it)
Run vive console as admin
Enable direct mode in SteamVR developer settings.

While still not perfect these changes have at least made games playable again.

At last, I hope you guys allow the users to have a way of keeping or reversing to the older versions of the drivers.

In a case like this, if my system restore fails, I have no way to play any game in VR on my PC and have to wait for another update who knows for how long...   this will be a real disaster...

Agreed, a rollback option is sorely needed. 

Further to my report that I submitted (20200604114557) it seems that disabling all overlays you may have running and enabling direct mode in devloper settings for SteamVR has improved performance, still no where near previous levels though.

Changing between room scale and standing had zero impact 😞

I'm also experiencing stuttering issues, seem to be mostly in Beat saber at the moment.

Hitting reset in the console seemed to fix it however when I  changed to roomscale this morning it returned, I have a feeling it's related. I'll investigate and update with my findings.
