I forgot to mention I don't use GFE at all. I don't install it with the driver. Absolute trash and telemetry nightmare it is.
Also if you haven't already figured this out, in Windows you should disable HAGS (if enabled), causes more issues than good.
HDR may or may not be the reason why you faced issues but with Nvidia I'm not sure anymore their drivers are absolute dog shit when it comes to open issues and the time it takes to fix them. Worse than AMD.
