I'm not super tech literate, is the VRAM section of this article referring to the VRAM patches valve was/is adding to steamOS to help optimize VRAM usage for lower end cards?

Pasted for convenience:

Mesa 26.2.1 & VRAM overcommit / cgroups

The kernel carries the full VRAM overcommit series along with the dmem cgroup work. The benefits of this include buffer eviction priorities, ordered bulk moves, VRAM claim throttling, protection limits, and a fast path so the compositor stops evicting your game’s textures.

Bazzite wires the userspace half up out of the box so there’s nothing you need to do as an end user to enjoy these features:

dmemcg-booster runs system-wide on every image

KDE images get plasma-foreground-booster-dmemcg

GNOME images swap uresourced for uresourced-dmemcg
