I use yamagi, triec q2pro but the current that i compiled from source has no option to invert mouse, thus unplayable for me.
(And may GOD HAVE MERCY ON YOUR SOUL, what is this, a flight simulator?)
If q2pro doesn't do it for you, try aprq2.Anticheat won't work on Linux.No real network tweaks to help the same way there is in something like quakelive. Just gotta lead your shots. At 150 you'll notice a significant delay, but it is more playable than newer games that try to compensate and have weird behavior.
