Ok I got it to work with +1 VT
Didnt take long to test and see this is not so good sadly, the flicker is just too much even if fps changes just 1fps.
Hopefully someday its possible to have gsync and ulmb at the same time without so much flicker because damn the few seconds it was normal it was so clear and smooth.

It's been a while since I last tried it. You're right. It doesn't work with +5 anymore, but does with +1. I edited my post.

Yep. It needs rock-stable frame times. RTSS is pretty much required to have a chance of it looking remotely useful. In-game limiters don't work too well.

I'm not sure what allows G-Sync and ULMB to be on at the same time. Firmware options?

Is there any chance the Acer Predator Z1 (Z301C Tbmiphzx) can utilize G-Sync and ULMB at the same time? (It's an ultrawide that can run 120hz ULMB). And since I'm talking about it now, how much of a problem can a VA panel panel (smearing, blur), I've only seen reviews Predator Z35; I imagine they'd be similar. Perhaps black-to-grey response times don't matter much. Pretty sure the ghosting and smearing will be too much.

A firmware quirk or bug or intentional easter egg that only gets triggered via a Custom Modified Resolution as the obscure "trigger".

You know, getting your hands dirty with Custom Resolution Utilities -- and modifying the video signal in a beind-the-scenes way, such as Porches, Sync, and Vertical Totals.
