Not sure about the parent, but my friend an I had exactly the same issue, both of us are on 16inch MBP 2020 (Civ 6 on Steam). Incredibly annoying once your laptop suddenly slows down and dies after 5h of gameplay. How is this even acceptable? Regardless whether it's a $400 or $3k laptop, I'd expect it to work when charging. I'm two apps (photoshop, lightroom) away from switching to Linux.

I would understand if $400 laptop had low power charger to cut price. But on $3k "pro" laptop it is just middle finger to customer.

Probably more to do with FAA regulations than anything else. You can't put more than a 100W batter in a laptop, and the charger is 100W (96W, I think), but modern processors and GPUs need more than that at full speed with all cores, leave along fans and SSDs and screens. My similarly specced desktop runs at 400W, not including the monitor. So yeah, we seem to have hit a limit with traditional chipsets. Probably why Apple is going full steam on their own ARM SoCs. The iPhones and iPads out now can do some pretty serious work, just imagine what could be achieved by bringing that power to the Mac.

  I believe the frustration is more due to the fact that even though the laptop is plugged in, the battery gets drained and after a while, it will simply shut down. I have had that issue with 2012 15 inch, 2016 15 inch, 2017 15 inch and heard similar stories from 16inch users. Reminds me of the early brick-sized mobile phones. Sure you could be wireless, but if you wanted to use it more than few minutes, you had to find yourself a power socket.

    I still find this a bit peculiar, I haven't experienced that in any of my previous machines, mac or not. Normally, I'd call customer support and assume it's an issue with my device specifically. HN saved me a bunch of annoying phone calls.

  The FAA has no restrictions on chargers, the restriction is on battery capacity which is irrelevant to this problem. They use 100W chargers because that's the highest allowed by the USB-PD spec, but Apple providing power supplies incapable of handling peak load on their laptops is much older than their use of USB-PD. They just seem to not care very much about the heavy sustained load use case.

  ARM seems like the way to go. I recommend comparing the energy usage of Macintosh II and Macbook Air. It's quite impressive (minutes vs hours).

I solved my few Windows dependencies with https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM... and a secondary GPU. (Might not fit your current setup but it was a game changer for me and my productivity so I can highly suggest it.)
