Hello, I just installed MB II and I joined a server. The game was working fine but all the other players were moving like they had lag. Someone told me to type /r_pri 10 in console because that can be the fix for the problem but now my game is not working, every time I start it it's just the logo at the beginning and the music in the background and if I move the mouse I can hear the cursor over the buttons. Does anyone know how to fix it or should I reinstall it? And what about that lag thing? Thank you!
