Call me out if I’m wrong, but my Deck is noticeably snappier after this update. TF2 is also smoother, which is weird considering the game hasn’t changed visually at all. Not even an update notice of anything major.
32-bit programs can’t use as much memory as 64-bit programs. Being able to use more memory means less loading from the disk. 64-bit also tends to be more optimized these days as most systems have moved to it already. In this case, I had no idea TF2 was still 32-bit.
I gave it a Google and saw what changes they have made, and it definitely explains the new feel. Frame timing is waaay better and the frame rate is more stable. They moved from a OpenGL implementation to a Vulkan one, from my understanding. I had to adjust my mouse sensitivity too, so they made some changes there as well.
You seem to have a misunderstanding of how Bazzite works. It's just a custom Fedora Atomic spin that includes things like the deck firmware updates, drivers, and gamescope. It does not run SteamOS in a container.
I'm surprised I haven't heard much about Collabora partnering with Valve before now. From reading their articles about it, it sounds like they're largely responsible for the Deck's update framework and for pressure-vessel which is designed to provide a standard linux container for games to run inside of (think of it like a flatpak but just for steam games).
Collabora has been quite active in the field, e.g. they're the prime developers of WINE's current Wayland solution. So it makes sense for Valve to partner up with them.
IIRC SteamOS development is mostly outsourced to contractors like Collabora and Blue Systems with Valve having only a handful of people to oversee the development and the occasional in-house developer.
Nice to see we can expect some improved update deliveries with Desync. Now, if only they could implement a way to layer persistent packages like you can with rpm-ostree...
