OpenGL is used for pretty much all graphics acceleration on Linux desktop - desktop compositing, browsers (booth 2D content and WebGL & WebGPU), games (also console game and windows game emulation), etc.

You can play games and use gui applications on the new M1 devices using Asahi Linux. Which means running Linux instead of MacOS.

The only caveat is that most applications won't be compiled for ARM yet, so emulation will still be needed.

This is in contrast of Apple dropping support for OpenGL on their devices, and using their own API layer: Metal.

Source? The mainstream distros already have comprehensive ARM support in their repos.

Asahi is working on a Fedora respin which will mean all your usual packages are a `dnf` command away.
