At first I want to say thank you very much for the port! I already bought some DLC's to support the porting.
I tested the game on Ubuntu 14.04 and 15.10 with NVIDIA 355 drivers (to see if it would help in recognizing joysticks, steering wheels and joypads but only my 15 bucks Thrustmaster joypad works:( ) and both work better than on windows. Maybe because there's no Battleye, advanced flight model etc. but it remains the fact that it works better.
My problem is that windows os (virus system) won't enter in my house anymore, so please continue mantaining the porting. Thank you.
