[Solution] Choppy mouse on linux

Well, I don't normally do the radical mouse movements I do while playing, so that's why I only get it at playing (and I do get it at every game). But if I try to reproduce it on the desktop, I can. It just doesn't happen without trying hard.

Yeah, but in my situation mouse moves smooth in desktop. And when i start warsow, mouse goes totally useless. I cant even navigate in warsow menus.

I do confirm that issue on warsow 0.42, USB mouse unusable (64bits testing gentoo linux)
Moreover the hardcoded stuff for keyboard makes my dvorak layout a pain. Should be a runtime option.

If i change "evdev" to "mouse" driver, mouse works smooth on warsow. But with "mouse" driver mouse works buggy in desktop.

games-fps/warsow 0.4.2
