@Jaus check your steam library and see if you have a program called "windows Mixed Reality for SteamVr [beta] installed. I suspect that is the reason you don't see the ..\MixedRealityVRDriver\bin\win64\OpenVRSettingsUX.exe in your folder list.
Alternate method: "[your drive]:\Program Files (x86)\Steam\steamapps\common\MixedRealityVRDriver\bin\win64\OpenVRSettingsUX.exe"
for those of us who still have the controllers in the box.

Some knobs don't actually move but changes happen, so far this is a very good mod...
Should be able to find a couple of programs if you haven’t already that will run a good stress test and make sure that there is an a problem since you’re not getting the megahertz out of the ram that you should.
