you have to type in "-shaders 0" at the end
if that doesnt work, download new drivers
if that doesnt work, get a clean re install
if that doesnt work, open up "default" in the Toribash directory in notepad and change the value of shaders, reflections, soft shadow, fluid to 0
if all else fails, restart youre computer
*make sure you have 3.06, tis on the download page
