What is benefit of GPU-rendered UI? In regular 2d apps where I can select enable/disable GPU rendering, disabling doesn't make app feel slower, but it drastically reduces RAM and VRAM usage (VRAM is the one I care about, as I run local models). Why so many UI frameworks brag that they are GPU-rendered?

Well, for one, it usually is much more energy-efficient: longer battery life, cooler computers, and more responsive under heavy (CPU) load.

Other people have different hardware and different goals. A year or so ago I worked on a Linux laptop that was dog-slow. If I didn't enable GPU-rendering for the UI, it competed for the very limited CPU.

Using less power is generally the main benefit. On lower end hardware you may also notice a performance difference, depending on what the UI is trying to display.
