I like this game.
When I press the fire button quickly it doesn't always respond/fire.
I've tried different mouse buttons and keyboard keys but fire is always abit sluggish and unresponsive.
Other commands are responsive like fish eye camera which I also tried on different keys.
I tried 1.1.4-1 aswell.
I use Ubuntu-64bit, GNOME 2.30.2
AMD Athlon 64 x2
Nvidia 8800 GTS
4 GB ram
