@DShib Watched your video, the skip is near the start right. It's much easier to see on a screen where you can move your cursor/aim in a straight line across the screen. I use destiny 2 & the character select page or character page, move in a straight line across the bottom & the jump is very clear, however as I said before it is hard to spot in video format, it's much worse in person.
Regarding the fix from yesterday, tested this morning & you're right, the hdmi3 trick is basically the same as having ALLM turned off & play on hdmi 1 or 2, BUT with a much worse picture. So you're better playing on hdmi 1 or 2 with it turned off. It even says in the description turning on the setting for old compatibility affects your picture quality so I wast going mad. @Loubear lol.
Don't know if it's bcoz we got the new router yesterday but the desync with it off is now barely noticeable, but the skip is still there with it on.
I'm convinced it's caused by the fact ALLM needs a 120hz screen & glass is 60hz & whatever it's doing to make that work is causing the issue & if that's correct they can't ever fix it, it's like making a petrol car run on electricity. So for now, it's do the plug on/off workaround or play with it off on hdmi 1 or 2 for best picture quality. Personally if I'm playing destiny I'll leave it off, I still need to test cod with it on/off but I'm willing to do the plug trick if it's noticeable, I played with it off & it felt ok, more testing later I guess 😞
