So... the people who were most likely to actually be using or benchmarking multi-GPU setups then? Not sure what you're implying by calling the lack of support a myth. Unsupported titles would often scale poorly, not at all, or even negatively. Even in supported games microstuttering and frame pacing problems were rampant, especially once reviewers started measuring and reporting frametimes and writing reports on multi-GPU pacing issues.
The problem of course is simply one of money. Even back during the peak of multi-GPU popularity the actual install size of users running gaming rigs with multiple cards was barely a sliver. Yet making the tech function correctly required a significant resource investment from AMD and Nvidia's driver teams in addition to the game developers.The root answer to OP's question is that both AMD and Nvidia spent years investing in their multi-GPU tech, but were never able to address the core issues hindering widespread adoption. It's not unfathomable that either of them could have eventually cracked the code that finally delivered the better (but not perfect) multi-GPU experience of mGPU, but pretty much every argument in favour of them having continued investing time and money into that development would likely result in reduced profits. These are giant publicly-traded corporations, which of course means they work for the shareholders, not the consumers buying their products. Tech like that would mean far more of your customers with previous gen products might look towards doubling their performance by picking up a second of the card their already have to drop in rather than buying the latest product generation when they're looking for an upgrade. Older cards would potentially be kept relevant for far longer. Buyers would be swayed to invest less into their GPU at the start and more into a motherboard with dual CPU-fed PCIe 16x slots for a future drop in upgrade, rather than spending that money to move up to a faster GPU.
Why hide behind PMs? If you've compiled a more thorough list of DX12 mGPU supporting titles than what can be found on existing wikis around the net, why not either help update those existing pages, or even just publish that information yourself for others to make use of?
What's the the totally "%" of games you think actaully supported SLI or Crossfire back then?
& then what's the total % you call good support ?
Without your answers to those questions. I'm not going to answer the rest of the quote.
