I tested open source to see what quality it had.
And I did the low-jitter kernel that was featured back in 2012 on Phoronix. One needs to measure actual framejitter here though, to understand it.
It did Doom 3, which I used for testing, in 72.7 FPS (low psychovisual noise refresh rate). Which John Carmack said was a difficult case, and that 30 FPS was regular on this. Reprioritizing (renicing) X was also needed for this. This was much better than windows at the time.
And tried realtime threads with audio, that made 0.33ms audio latency possible. In comparison Windows on my current computer has 10ms latency(!). I also had a Mac Mini that could do 1ms latency.
In these days the Linux kernel has gotten many more realtime components. And has the EEVDF scheduler coming. It all seems very optimal if one likes low-jitter computing. (No interruption, but smooth flow of operation).
From what I understand one can prioritize interrputs aswell with that, getting even better results.
For a desktop PC, one may argue that 200µS jitter, is close to optimal.
I would also use the Oswald Google Font here (as on this site). And unified open source, demoscene, social networking, etc. Really all culture from this point of view, as a social O S, with file publishing and file commentary, integrated with online payment methods.
And called it Bud X. Which would be a modern Amiga like thing, culture wise.
I also use Presonus Studio One, that is in beta, for Linux. Studio One 6.5 for Linux | PreSonus Software
