I doubt they’re all full downloads. Flatpak does a lot of deduplication.

It downloads every single of them fully. Took 15 minute or so for all the packages or longer. This is going on since I started with Flatpak. The Nvidia drivers are not de-duplicated or partial downloads on my system.

You can see it in your screenshot as well, >140MB downloads that are marked as completed even though only a few megabytes were actually fetched.

That's not the one I am complaining. The drivers are the ones named as org.freedesktop.Platform.GL32.nvidia-xxx-xx-xx . These are the different driver versions of Nvidia and each of the 7 versions are 340 MB or more and are always downloaded fully. You can see each of them like 340,9 / 341,8 MB. What you was referring to is not what I am complaining. The extraction of the archives and installation is quick. Every other package is quick, only those take this long.

but the sheer download size isn’t the problem in my experience. Not great, but not as terrible as it may seem.

It isn't a hard problem, but very annoying. Not sure how fast internet access you have, I have under 7 MB/s. And only counting the Nvidida drivers through Flatpak alone is 2.3 GBytes. Imagine adding all the other updates in Flatpak, plus the system update of my OS itself and the DKMS. It adds up a lot.
