The glass transparency effect is just very computationally expensive.

The glass UI renders on my Apple Watch 6 just fine and that thing has probably 0.5% the GPU power as the Macbooks.

There's visible lag & stutters opening the control center on my Series 10.

Likewise, while it performs "fine," interacting with the UI still feels sluggish on Tahoe on my M4 Pro compared to Sequoia. I still have another M4 Pro with sequoia on it and it's a night and day difference, in favor of Sequoia.

There may not be any real performance loss but there is definitely UI latency and it's very noticable.

Like others have said, check whether you have any Electron apps that weren’t updated with the latest Electron framework. Both my M1 Pro and my work M3 Pro don’t feel any slower (unless I open an offending Electron app). I was updating a Mac that uses Sequoia yesterday and it didn’t feel any faster.

Your watch also has a screen resolution of (3024 * 1964) / (368 * 448) = 36 times less than a Macbook, so it's all a wash. Except the wasted coulombs.

It also renders on my M1 Macbook just fine as well for what it's worth. If it's running slow, it's because something is bugged out rather than the UI inherently being too heavy.

I just don't understand how if Visa could render its transparency efects smoothly on Intel 920 grade GPUs with 128mb of ram.

That's not how I remember it. Back in the day the first thing you did was disable the Aero stuff to claw back some performance on Vista.

That said, who knows how efficient the implementation is compared to other changes in iOS 26. I turned liquid glass off with "reduced transparency" because even 1% extra battery usage for it would be too much even though I kinda appreciated the new look.

>>That's not how I remember it. Back in the day the first thing you did was disable the Aero stuff to claw back some performance on Vista.

I remember it being kinda like placebo - you did, you marvelled at how much faster it's working, but in reality nothing changed. I really liked the look, and it did run smooth unless you had something below the minimum spec(which a lot of people did at the time).

I mostly disliked Vista for a number of reasons, but the looks were incredible. I was actually blown away at the beauty

I liked aero too, XP was too fisher price.

XP Media Center Edition had a pretty slick theme, not at all toy-like. To say nothing of the Metro interface in its titular app, though it seems Metro was kind of a dud when they tried to apply it to other apps.

Vista problems were largely nvidia driver crashes and low spec machines. Otherwise vista was fine.

Yes, though I think it worth noting that at that point "low spec machines" was like 80% of laptops and maybe 50% of desktops. It also really hurt when you went from XP which ran great to Vista which noticeably dragged on your machine.

My friend had an Alienware laptop which absolutely screamed with Vista

Vista did translucency and a statically positioned reflection mask, whereas this glass effect involves refraction/tinting that samples from surrounding surfaces.

It barely handles that, and even the M5 still cannot cope with 8khz mouse input coupled to a high refresh rate (>240) screen. I laugh every time they try and sell us on these things being able to play games

Even looking at pro CS players, a single 8 KHz entry is found in the table at https://liquipedia.net/counterstrike/List_of_player_mouse_se..., so it's a really odd hill to try to die on.

They really are great gaming machines from a hardware perspective. I wouldn't bother with an x86 laptop for gaming if it weren't for the software (mostly DRM) side.

That is wildly outdated, everyone is using 8khz input now. Keyboards too. This also completely ignores the 600-640hz monitors they are playing on.

Even 1khz mkb input on an apple silicon mac connected to a 500hz screen has insane utilization just doing shit in the OS. They are also struggling with variable refresh rate, improperly dropping down to the minimum (as low as 24hz) with jarring, jagged jumps up to the maximum after a few seconds of use.

This is a solved problem on both windows and linux. Even Asahi does a better job.

No, not "everyone" is using 8 KHz polling now... it breaks a lot of game engines for no benefit (even 4 KHz) but is heavily marketed because higher numbers. Worse yet, 8 KHz eats the kernel with interrupts (even on my 9800X3D) instead of letting the game run as fast as possible.

High refresh rate monitors are great, yes, but those are still sub KHz - you're talking about polling a mouse at 13x the rate of the highest end esports monitors as some minimum bar for when a machine can be for gaming - get out of here with that kind of artificial gatekeeping.

No complaints about Asahi though :).

Not "everyone". The G Pro Wireless is one of the most popular mouses and polls at 1KHz, and it works just fine. Polling a keyboard beyond 1KHz is utterly useless. The only time you're gonna want more fidelity is with stuff like Snap Tap, which is considered cheating and is banned.

In a similar vein, >120Hz screens are of doubtful utility. The performance gain is insignificant, considering top human reaction time to visual stimuli is ~150ms and the jump from 120Hz to 240Hz is -4.17ms, 1/36th or 2.77% improvement.

Even then, most pro FPS players also still play on 200-800 DPI when 1600 DPI and preferably even 3200 DPI is much better. Those low DPIs are purely cargo culted from the 2000s era CS Pros their .cfg, when sensors were still pretty crappy, and those players are effectively running lowgrade mouse smoothing.

Uneducated gamers are kin to uneducated audiophiles. Stop drinking the snake oil.

?? isn't it objectively the fastest ST core out there, topping MT benchmarks as well? Depending on the variant the M4 plays cyberpunk at 50-120fps so what are you saying?

The problem is the edge cases where people use hardware capable of absolutely ridiculous things that nonetheless are common-ish on Windows and expect macOS to be capable of dealing with as well.

(Don't get me started on macOS and the un-disableable mouse acceleration override coupled together with Steam Link...)

LinearMouse is a bandaid for the latter problem.

Benchmarks are one thing. Real world usage and I/O are another.

There is no world where 50fps is acceptable in any game in 2025. Flagship GPUs on high end systems running Windows manage 4k @ max settings north of 60, nearly double that with RT off. To achieve anything close on a mac, you're dropping down to 1440p, at lower settings, with frame generation.

Lol ok buddy you’re not accounting for the 50W vs 500W difference. Gotta compare to windows laptops on battery.

They’re about the level of a 4060 https://m.youtube.com/watch?v=LWfM7Ktsal0
