Over the course of more than a year and a half, I have run my Pimax 8k X on an RTX 3080, 3090 TI, and 4090. I have also run it on a 10700k/z490/DDR4 and 12900k/z690/DDR5, ran the 3090 TI on both of those. Run on W10 and W11 with the 3090 TI too.
So no, I definitely know how it’s supposed to work and it’s not just I am not noticing it. It’s just not happening on my system.
