there are games, that don't use any shader technique and still display bumb maps (like outcast from 1999 i think), or depth of field (silent hill 2 from 2001), and look great. it's a pity that you are forced to have an up to date graphics card in order to achieve this in gamestudio.... unless you are a very talented programmer and can implement these visual features otherwise... which i am not.

but of course it's not just 3dgs, most games nowadays use shaders for effects you could aswell have let your cpu compute, which eventually either leads people to buy a new card. or a ps3/xbox360 instead
