Got my 15 year old Thinkpad X300 out of storage. It's a 1200mhz Core 2 Duo w/ 4GB RAM and Intel 965GM graphics.
So like, pretty damn slow, but it does do GLES 2.0!
The GTK 3 based gnome-terminal in Fedora 39 took 3m59s to cat a 650mb text file.
The GTK 4 version with all of my and others patches applied and using OpenGL took 2m21s.
A reduction of over 40% on ancient hardware.
So when people say that GNOME doesn't care about old hardware, point them right here.
