i just downloaded it and it is very slow and the sound is deads jumpy. why is this?

my computer has enough ram and all that but the game is slow, even in the menu's, the mouse is slow

please help

did you try to disable some effects ? and openGL 2 shaders ?

just give more informations about your hardware plz, 'i have enough ram' is not really helpful

If you are using windows, try (re)installing your graphic drivers. Get from the homepage of your graphic card manufacturer, the drivers windows update install don't support OpenGL.

But more informations would be really helpful.
