Not a big gamer, myself, but it seems like Valve has done a lot of work to make many (most?) Steam games run well under Linux.

Drivers have come a long way, and a lot of things just work, but it can definitely depend on what hardware is in your system.

I think that the answer to this depends on the audience and the topic or nature of the discussion.

I prefer precise, technical language if the audience has experience in the topic. You can save a lot of time by not explaining things that the readers should, reasonably know.

I think simpler language is appropriate for a more general audience or higher level discussion.

It can be challenging to find the right balance on a forum, like this, where you don’t necessarily know who the audience is.

There are simpler solutions that are just a php script on your web server if you’re only interested in IP address (I couldn’t find a good example quickly on mobile)
