For those who play CS:GO and Dota 2 competitively, Linux isn't a viable option because CEVO and ESEA don't have clients for Linux. That's ignoring all of the bugs and quirky behavior that come with the platform. ALSA has a 10-100ms delay and for a game like CS:GO that relies so heavily on audio feedback, that's inexcusable. There are also issues with mouse input, lag, and random frame drops on Linux that have lingered for years.

You'll see all kinds of posts showing Min/Max FPS and how Linux beats Windows at this game or that but you rarely see any mention of Average FPS because they're usually pretty awful.

What is this you say about audio delay, I have had no such problem with Pulseaudio or Alsa

Just because you don't experience an issue doesn't mean it's nonexistent. A quick google search reveals that it's quite prevalent.

It's non existent in many cases, but not all. If you need real time sound, you'd use Jack, not PulseAudio.

I never said anything about PulseAudio, I said ALSA introduced delays. JACK uses ALSA the same as PulseAudio.

In any case, it's the game developer's choice and not mine. Yet another problem Linux has for developers is that there isn't always a clear choice and the flavor of the day may not be the best choice long term. That's why frameworks like Qt and Unity are so prevalent because they abstract a lot of the crap away.
