Firstly you have to understand how much of a hassle it is to have to go take apart 2 computers to remove the graphic card from one and to install both into one, have to go dig out some pci-e power cables from storage:

All this mess to gain access to find the 1 box with the extra power supply cables…
Then remove my harddrive bay to access the power supply, undo the cable management, etc just to retest crap or provide you with additional “proof” requests as there really isn’t any reason to doubt the OP findings in the first place:

So it’s something hard to find motivation to do; to mess up your dream pc build and then waste more time afterwards be forced to put it all back together again for both PCs and put everything back into storage.
This is simply because I do not own 10 series cards or other graphic cards anymore other than the 30 series cards I currently have… so common sense would tell you: I can only speculate on this feature working with older cards, rather than actually test it myself to see if it actually works with older cards.
So obviously as users report in and state it didn’t work with older cards, I take their findings into account and update the “goal post” as you put it.
Anyways, now that I have decided to do all of this:
Some sad news, it appears that this feature is dead in the actual launch of Shadowlands (retail) as opposed during pre-patch when I originally tested:

As you can see, 0% utilization on the second RTX 3090 in Retail.
However on a side note:
In the Shadowlands Beta, it is still working:

As you can see both are utilized and sharing the load.
As for if there’s a way to get it working again in retail (maybe fiddling with settings?), i honestly can’t be bothered and lost all motivation as compared to when I was stuck with only RTX 3070s trying to meet my 120hz 4K monitor’s refresh rate, as now that i have a RTX 3090 in my system, one is good enough for me as that achieved my goal…
So if someone else wants to carry the torch, by all means be my guest. As this is the last and final time I will ever take apart my computers to test a feature in which I no longer have any use (or interest) for.
now I have to brb while I re-cable manage, put my computers back together, and stuff everything back into my storage closet >.>
