I've been forwarding an AMD GPU to both Windows and macOS for literally years across multiple Asus motherboards and, except for the specific problem of host sleep/wake, had no problems whatsoever, even considering I work under GPU-passthrough VMs whole-day, every-day. Perhaps try a recent Asus motherboard?

Yes, you would have to buy as many cheap, secondary GPUs as the number of virtual machines that you want to run in parallel.

Sure, I don't blame you - my point was that the only truly usable GPU virtualization solution available today is GPU passthrough and that GPU passthrough is much easier to setup than it is commonly perceived.
And if I don't want to or can't afford to buy new hardware?

Okay, but for the poster you're replying to it is not available on their hardware.
I also have an AM4 ASUS board (is that recent enough?) and earlier this year, ASUS decided to completely remove any mention of this board from their site, as if it never existed. So no bios updates for me I guess? No idea if it is up to date or not or if my CPU is even supported...

Except that cheap GPUs are... cheap and not very powerful, so depending on what I want to do I would have to buy a bunch of expensive and powerful GPUs (or go back to rebooting VMs to switch). And there are only so many PCIe slots on my board (2x8 and 1x4, the latter of which is already in use by a non-GPU card). Running them in an x1 slot also doesn't sound like a great idea.
I have tried to run it but gave up in the end after breaking bios updates and not wanting to spend even more money on another fast GPU.

Maybe your board was only disappeared on some locales? Maybe see if you can find it on asus.cn or one of their other regional sites (translation service required, but you can probably muddle through)
I haven't seen that in a long time, amd640 super7 chipsets got disappeared, but back then you could still get the bios updates via ftp, the boards just dropped off the website.
