Torque3D 3.8 will be soon released with many nice nice fixes for Linux especially.
A bit of a pity that development has slowed down, but according to another (unnamed
) Torque3D developer it is also because fr1tz is running it a bit too much as a one-man show. Wasn't meant as criticism, but rather his workflow on github makes it difficult to follow up on development, and most stuff is implemented as C++ rather than the easier torque script. The latter will btw get a speed boost soon (maybe in 3.8?), so maybe it would be possible to use it more for the simple gameplay related stuff?
For me I really wanted to contribute in the art department... but since I am currently located too far away from any sort of playable server (besides the general lack of players) I really lack the motivation to contribute to a multiplayer-only game
