I have in my possession an ati radeon 9600 graphics card, which supports shaders, but apparently, it won't apply them when i play toribash.
now, we have all heard of cases in which they turn the shaders on, and then the screen goes blank, or the game crashes or something. my case is different. when i turn the shaders on (menu>setup>options>shaders [on]> OK), the screen goes blank for a few secs, and then it returns to normal mode. i go check the options, and the shaders are off. what can i do?

Edit: i reinstalled the game, but it still doesn't work.
