I asked this question:
http://gaming.stackexchange.com/questions/123655/how-can-i-optimize-the-performance-of-the-tf2-linux-client-on-an-old-low-spechttps://gaming.stackexchange.com/questions/123655/how-can-i-optimize-the-performance-of-the-tf2-linux-client-on-an-old-low-spec
And got a lot of quick feedback, which is great. Unfortunately, all of it 'discusses' the question. It's not all critical - there is at least one commenter and several voters who seem to think it's a valid question. But the majority of commenters (and narrowly, voters, as of a minute ago) seem to take issue.
Questions have been asked that are quite similar in most respect - questions that have answers, that have upvotes, etc. Multiple questions have been asked about the performance (and optimization thereof) of this very game - for Windows. Questions have been asked about very specific issues with Linux ports (even Betas).
I guess I just have .. timing.
My questions detractors mostly seem to say that it is too specific/narrow, or that is can't be answered 'cause Linux is just like that'.
I get that by SE design, questions should be able to help others. In my view, I presented enough details about my situation to provide the basics for an answer - but the answer could/should still be applicable to anyone in a similar situation. That may not be a lot of people, which I think is why some people have a problem with my question.
Linux gaming is still a pretty small share of the market, especially if we mean the kinds of games people here on Arqade usually play (I don't see many Zork questions). So, if 'helps too few people' is a problem, and my question would have been ok if it were for the Windows (or OSX, maybe) version, why do we have a Linux tag? It seems like most Linux questions will apply to a small subset of current Arqade users.
Edit:
To clarify, per the current hold:
If 'Too Specific'/'Too Localized' is a valid close reason, and many users here seem to think that Linux technical questions (almost?) all fit that description, then when is it appropriate to ask a Linux-tagged question?
Only when there are gameplay differences between ports?
Edit:
For those answering/commenting about Linux being some volatile mess with infinite unique configurations, please remember to justify that. I'm tempted to ask what any of 'the haters' know about Linux, or how many of you have used it for any length of time. The more practical way to say that is: You don't need to use Linux, but you do need to explain this 'fragmentation', and why it is a dead-end. (That's what detractors call it for Android - which doesn't seem to suffer a lack of games.) Yes, Linux can come in weird shapes, but many companies deal with this (including closed commercial applications). The solutions don't always work 100%, but I'm not trying to run on a toaster/dead badger/router.
