The Metal (Apple) or OpenGL/Vulkan (Gtk) renderers are not that important for apps that were fine with software rendering for years. The final composition of framebuffer is being done with hw anyway (for most cases, unless you have a really old hardware with non-working opengl 3 or so).
The downscaling, when done properly, is being done with output encoder, not with GPU. It should be transparent for anything graphic card, that came with DP or HDMI port. Maybe except original rpi.

In my experience it becomes an issue if you do something like maximize the window on a 4K screen, GTK3 has noticeable slowdown there whereas GTK4 is faster.
