I'm really not sure Apple's reasoning for using such display that has pro-motion but has awful lag times. I don't understand it. It doesn't have a huge effect on my work for yet... but it is very odd for sure.

The colors look so good when watching video, but yeah the ghosting…it’s odd they chose this display. Because videos look so good I’d be fine with it if they’d fix the promotion bugs. Scrolling in podcasts and App Store look fine.

No one seems to have discussed the elephant in the room. The new displays are amazing, but when it comes to motion they are awful. They have the worst lag times of any modern laptop screen. So what you’re seeing isn’t promotion not working, it’s the terrible latency of the displays. It doesn’t bother me too much, but I definitely noticed it while scrolling compared to other displays. In that specific regard it’s worse than the MacBook Pro I replaced. Don’t expect Apple to fix it since it’s a hardware limitation, not a software issue.
This is a separate issue from what's being discussed here. There's a clear difference between the scrolling in Chrome and the scrolling in Safari. And that's 100% software. If that's not clear enough, download something like Dolphin Browser from the iPad/Mac store and the difference is even more staggering.

No one here is confusing this panel for an OLED one, where the response time will be significantly better. Yes, THAT's a hardware issue.

The fact is that there are apps here where the scrolling is much better than what's displaying in Safari. Chalking this up to a hardware issue is basically giving Apple an out for not fixing it.

EDIT: Just installed 12.1. Using Safari now, I can confirm earlier reports that it is definitely better than 12.01 and ProMotion is working. However, the inertia scrolling is still not up to par. In comparison, Chrome inertia scrolling (and scrolling altogether) is just a tad bit smoother. Not sure why it's so difficult for Apple to get this right on their own software. Regardless, Safari is definitely more usable with "controlled scrolling" than it was previously. Whereas before I could tell that it wasn't hitting 100+ when keeping my fingers on the trackpad, now it is completely smooth. They just need to get the inertia scrolling figured out. There's still some stutter there.

And you shouldn't need a framerate counter to see this. It's not perfect, but the difference was clear right away for me. I may go back to using Safari now.

I’m going to go try chrome and see. I’m glad 12.1 fixes it. Maybe they are trying to save battery life or something. I know chrome is a huge memory and cpu hog

coming from from an iPhone 13 pro, I'm actually shocked by how poorly high refresh is handled on these new MacBook pros. I tested the dolphin browser someone had mentioned and the difference is stark.

an interesting thing I noticed, however, is the "inertia scrolling" option in system preferences doesn't seem to apply to any iOS ported apps (including native ones like messages). they all continue to scroll with inertia (totally smoothly) regardless of that setting. so my best guess at what's happening is anything that was originally coded for iOS uses a completely different implementation of scrolling that has been designed with high refresh in mind. meanwhile desktop apps seem to use this legacy scrolling that clearly doesn't work with promotion.

That sorta launches me into a whole other tirade of discovering that almost every major iOS app I would look to download and use as a stopgap for this issue is unavailable. And that's despite apple pitching apple silicon Macs as having access to the iOS App Library. Meanwhile that access seems almost exclusively limited to junk apps.

I think your eyes need a software update if you think promotion isn't enabled on 12.1 RC for safari and chrome.
If you say so; it’s not smooth at all same as my intel one

Well then you have one with a defect because there a bunch of people who say that promotion is working in the RC (Although not perfect on safari due to a few jitters while scrolling here and there. Chrome is perfect.)

Exactly. According to Notebookcheck the 14" is twice as bad than the MBA in response time. Almost negates the ProMotion sadly. It's almost as if Apple added ProMotion so they could cheap out on the display panel itself.

EDIT: wanted to add the 12.9" MiniLED IPP has much worse response times than the non-miniLED IPP 11" so if that's an indication of things to come I'm not sure Apple is headed in the right direction.
Moore’s law - the technology will only continue to improve. MiniLED is promising, and the fact that it’s being adopted on a mass scale is a good thing. Look how far OLED has come. If you don’t like it now, return it and wait for next years release. Apple probably added ProMotion to unify its Pro lineup. - with the iPhone 13 Pro getting it this year as well.

I can confirm, Safari 15.2 is scrolling at 120hz promotion.
It really isn’t and chrome isn’t to, I don’t get how some of you think it is, they didn’t change anything in safari and if anything it was in the preview one and they removed it, go on MR site and scroll it’s not smooth

I think the main problem is images and stuff on a page as if your on a site with just text it’s smoother but with any graphic etc like with MR it jitters it’s not like the iPad that’s butter smooth

Promotion on scrolling, I didn't say self motion like on UFOTest, animation, or video..

It's 120hz man. All I know is that I've been using Chrome ever since launch day because of how bad Safari's scrolling was. And now I'm back to Safari. I'm sorry you can't see it. It's not perfect but it's better than 12.0.1 And if you're talking about the MacRumors main page, the scrolling actually looks better with images versus text IMO. Not sure what's wrong on your end.

12.1 is better than 12.0.1, but scrolling the same sites in dolphin is still noticeably smoother, even ones with lots of images.

Edit: another issue I'm noticing now is connecting an external monitor (only tried hdmi so far) causes the internal display to drop frame rate pretty substantially (everywhere, not even just web browsers). and this is on the 32gpu m1 max, which... is pretty disappointing if it can't handle plugging in a single display without performance degradation. However I think this just started after 12.1 so hopefully its another bug?

I can't see a huge difference between 60 and 120 when scrolling tbh. I don't think it matters a ton. Makes a difference when gaming, but for scrolling? Eh. It's cool but not that important imo.

I thought that too then I experienced the 120hz scrolling in dolphin and I was like. Oh so that's what I've been missing this entire time!

Thankfully on 12.1 . Chrome scrolls near 120hz. Very little dropped frames by my eye I think. Compared to 12.1 beta 1 which drops frames everytime especially on inertia scrolling

With 12.1 the scrolling refresh rate seems to be up to 120hz but it doesn't reach it consistently. They still have to optimize it. My 2018 iPad Pro scrolls more smoothly.

yep. its all over the place at this point. especially if an external monitor is connected on my system. also the monitor has started glitching out constantly. I'll have to test my old laptop to see if its the cable, but it started almost immediately after 12.1

12.1 is a huge improvement from the initial Monterey builds, as well as the first 12.1 beta. Safari is nearly there. Small stutters, but an obvious improvement. Chrome seems worse to me than Safari. Glad to see they are working on it, even though the release notes continue to not acknowledge the issue.
