use shaders.. to use them to to setup and tick shaders..
the different shaders are located in the toribash folder, u can find em cuz im too lazy to do it lawl.. you need like, 128mb video memory or over to run shaders, if it doesnt run and u have 128mb, or over, update your graphics card, look up on youtube how,
if you do not know how to check your graphics card, run "dxdiag" and go to the graphics/video << (dunno what it says) and it will say ur graphics card
if you can run shaders, type in /lws (theshadername.inc)
Good Day Sir ;)
