This is not what this hotfix is about:
My 2070 SUPER VR settings and suggestions (Index - SteamVR) 🟢 - #40 by CptLucky8
No I never do because NVidia is documenting you can install any driver version over any other (they fixed this installer problem about 2 or 3 years ago IIRC). Isn’t a clean install wiping out all your custom profiles like I’m suggesting doing manually above, or is there anything else with it?
The thing is that they’re introducing a new feature (background fps limiter) in a driver version officially, but this feature was already working and implemented in code in a previous version. It could have been there left over from a “work in progress” piece of code, or it was already there but only added the UI for it (and the official announcement) in a later driver after more internal tests. All this is indicating to me there are probably much more code running but not adjustable in the UI and this might be one of the many reasons there is some variability sometimes on the same system from day to day, or among different user’s similar systems.
