Just updated to COSMIC beta. Totally forgot I was running alpha for months. That's how good it's been.
Linux users should give it a try.

Redox OS performance is steadily improving. Here is 1080p video being played on a 1440p display. Most of the CPU usage is software video decoding, with the orbital windowing system adding minimal overhead. A careful look through the CPU times can verify this. 1/2

Yesterday I went through a ton of issues with Redox OS on riscv64. I was able to get everything compiling and working but netsurf, which has unusual soft/hard float ABI linking issues. Here is cosmic-term showing screenfetch output.

I have just compiled Rust code for bare-metal SPARCV8 and executed it under Solaris 2.6 on a microSPARC-II.
I suspect that no-one has ever done this before. Literally no-one.
