Got it! You actually have to disable hardware acceleration in settings to activate the 120hz, bizarre
Whaaa? Hold on, trying.

EDIT: what the hell! Really? NO hardware acceleration and it's totally smooth? Lol

EDIT 2: huh so downside of this is it's using a lot more CPU to scroll which probably is not going to be great for the battery

Well, and sites like Google Maps are crappy, but hey at least it works

Oh yeah look at that. Doesn't perform very well lol. I found another post on the Chrome dev forum where someone else mentioned turning off hardware acceleration too. I guess it is a global issue and not something wrong specifically with my machine.

I wonder if other browsers like Edge and Firefox have this issue.

I found out that even if you have chrome running but without any windows running. And you sleep it. When you wake up. As long as you go to full screen it'll go to 120hz. For me it works usually. But yeah it's kinda weird how it bugs out and it stutters or it's stuck at 60fps

Edge works just fine

I know right? Also it does not work on Chrome Beta, Chrome Canary, but works on edge ?‍♂️
If I had to guess it'd be because Edge is actually behind since Microsoft has to wait from Chromium releases and then adapt it for Edge and release it. Probably something that Google did just recently broke it, since it was much more consistently 120hz before.

Writing to say that since the OS update Chrome has been broken.
Not just Chrome. All Chromium based browsers (Edge, Brave, etc) appear to be broken as well. Don't know if it was the 12.2 update, the Chromium v98 update, or both.

I'm back to Safari for everything now haha.

12.2 has really fixed a lot of issues with the new mbps, I can now say I finally enjoy using this laptop way more. I personally use safari.

For some reason Chrome is back to 60Hz for me on 12.2 but I remember 120Hz was working well a couple of days ago. Maybe Chrome got updated. If I disable HW acceleration it's back to 120Hz but it uses more CPU.

Same experience for me, I don't know if it was 12.2 or Chrome 98, or both, that broke it. Hopefully it gets better in 12.3.

Not working in Chrome 98 with 12.2.1 for me. It will work if I disable hardware acc. But then maps and other sites that use HtML Canvas are slow and choppy. The weird thing is it works in Incognito mode.

No issues with my testing - 120fps/120hz Safari, Edge, Chrome, Firefox. I did turn off Experimental Feature rendering near 60hz

Everything's been buttery smooth for a long time for me these days. Was rough at launch but it's been fixed. I don't use Chrome though for anything but a secondary browser for troubleshooting.

Chrome is rendering 120hz (if you check testUFO) but still stutters when you scroll with a trackpad, likely because however they track inertial scrolling is still stuck at 60 hz.

Is this still an issue. Or has this been 100% fixed? Scrolling still painful for me.

It seems to be much better with the latest software update (was it 12.5?). Before that it was a bit stuttery for me. Seems back to being buttery smooth again now.

Safari just works fantastic. Like others i have stopped using Chrome as there are intermittent problems; Safari has come on leaps and bounds so I'm not particularly bothered.
