No. I really don't.
I have a discreet GPU on this system, which have the capacity to to pretty amazing rendering and processing. There is NOTHING in the daily use of an operating system that would saturate the GPU.

Would you argue the same about a GTX 9 or 10-series Nvidia card running Windows? (those are also aprox 7 years old)
They are aprox 7 years old so you shouldn't expect it to be able to run Windows? right? Or do you seriously argue that Monterey has so much amazing eye-candy that it requires a fresh new discreet GPU to handle?

I have the same experience with my system. No spinning drives on the 2015 Macbook Pro. I don't have any numbers to argue against your "extremely rare" statement, but I suspect you don't have any data to support your statement either.

I really don't know what is going on, but the effect of a clean install with Monterey on my system is ridiculous. I click on an application and it takes a long time to load. Reverting to Big Sur and it's no problems at all. Fluent animations are stuttering all over and the entire system seems sluggish.

It's true, but I don't think it's a good argument.
Microsoft manages to support thousands of configurations with their OS. For Apple to support the handful of their own systems shouldn't be too hard, but I think this is more a question if they are actively sabotaging older systems. To force people to upgrade. That is a dick move, especially since they try to portray themselves as an environmentally friendly company.

Macbook Pro have a really fast SSD (3-4 times SATA speed), so I don't hink that has anything to do with it.

I've tried a fresh install with only vmware fusion. I don't know, maybe they are targeting systems in countries that doesn't have a track-record of doing class action lawsuits?

That is weird. I got the quad core i7 and discrete gpu.
Did you upgrade late? or did you try the first few versions also? I'm wondering if they might have fixed the issues and I should try again.
Not getting my hopes up. Sort of settled on using Big Sur until it was EOL and just move on. Can't really complain on 8-9 years of updates (well.. of course I can, and do).

That sounds plausible. I guess Hanlon is still going strong :)

Or they knew what would happen and did it anyway. Who knows.

Actually it is my first mac, and I've had laptops since passive LCD screens were a thing. Mostly at the high-end. Compaq, HP, Dell, Toshiba, IBM, Lenovo, Sony, etc

The carbon fiber Vaio I had before it was delivered with Windows Vista and had a hardware switch to select between running the discreet or integrated GPU.Which I kind of liked. Being able to get some more time out of the battery when on the road.
Windows 7 was released a few months after I purchased it, but Sony never bothered to create working drivers for it, so I was stuck with Vista. Also, couldn't get that switch to work with Linux at the time.

So I'll give Apple that. They do upgrades WAY better than Sony did.

I would bet money on the only change from the last time they got caught was that they realized these "features" needs to be vagely connected to some other feature, so they can be "explained".
"No, it stutters on older hardware because we need to supersample the gyro* in case the screen tilts so we can adjust the flow better" or some bs.

*no, it doesn't have a gyro, i know, that was not the point

It's a clean install with Fusion.

I know you are trolling, but branding is important and Apple branding is actually pretty good.
I mean, have you looked at other vendors?
Take Sony for example. They have thousands of different PCs with names like VPCSE2AJ or VPCSE27FX. They are basically supported with drivers for 6 months and then forgotten. Meanwhile, people talking about purchasing a MacBook Air don't need to care that much if it's a VPCX390141 or a VPCX481941 because it doesn't matter for most people. They know what the Macbooks Air is about and they know what the Macbook Pro is about. Naming stays the same over a decade, so people get used to it. I wish other PC vendors did the same.

Now, if Apple sucks or not, I'll leave that to everyone to decide for themselves. I've been an avid PC user for most my life, but been quite happy with a macbook pro a few years. But think might be time to switch back to PC laptop again. We'll see.

This has nothing to do with high cpu load, but thanks for the lame attempt of a personal attack.
It stutters when swiping between desktops/full-screen-vms even when idle.

I have a 2015 Macbook Pro with top specs at the time. It's still working fine, but when I upgraded to macOS 12 (Monterey) everything slowed down to a comical degree. Just swiping between desktops/VMs became stuttery and sluggish. Everything is slow as molasses. Starting some application could take 100% more time.
I downgraded within a week and started to look at System 76 for when Big Sur is end of life.

I'm having a hard time believing this is because of new awesome features in the OS. More likely is a "Let the user know they have an old laptop so they start to think about upgrading"-feature.

I heard somewhere that Emoji was the deciding factor in getting the original iPhone to become hugely popular and also getting people to upgrade (and look forward to) each iOS update.

Session handling can be hard. Using a super secure federated authentication followed by a braindead useless session handling mechanisms is not unusual.

In a sense it's a bit like encryption: the golden rule is "Don't roll your own"
