DX12, VRAM usage. A work in progress: Sharing my settings

Ok, yesterday since my max voltage is 1150, I left it alone.
Upgraded to the latest AMD drivers.
Managed to get RdrThread to 10-12ms, I had to restart VD/SteamVR several times while the sim was already running and one of those times it lowered and was GPU limited(there’s something going on with VD/SteamVR).
Well I thought it would be great but turns out that led to having some kind of micro stutter of sorts. Where the objects are passing by but go back and then forward in a split second and then repeat that 1-2 seconds later. Tried many settings but couldn’t remove that behaviour.
Next sim start and I was back to RdrThread 26ms and all smooth without any rubberband or lockups…
Don’t know what to say honestly
