@miner29 - if your reply was directed towards my post, just above yours, then first off thank you for weighing in... I should add that per the nVidia control panel we're still using driver package 470.05, and per device-manager's info the timestamp on the driver file is still 2021-02026, so I believe I've ruled out Microsoft being helpful with a GPU driver update. (Also, I looked at update history and aside form the monthly cumulative update, nothing ease was applied yesterday. bummer.)

That said, I'm not averse to cleaning up existing the nVidia drivers package using DDU followed by a reinstallation of the same to see if anything changes.

In the meantime I did get t-rex going to see what it thinks. Both cards are hashing and t-rex was able to set the memory and clock speed deltas, and the clock power delta. Of course nothing's perfect - it is claiming it can't see the temps of the graphics memory so I can't specify a fanspeed range based on mem-temps. IDK if that ever worked because I've never used t-rex for ethash before and heck, I'm not sure I want to switch because t-rex doesn't support AMD GPUs like PM does, which means I'd have to run PM for AMD and t-rex for nVidia on this mixed GPU rig. Yaay.
