i have a card that supports shader model 2.0, and i am using A6 commercial (6.60). i am not sure what you mean by graphics options. i am a total noob when it comes to shaders. i think my problem is, when i build a hmp. i size it too big on the level and the shader doesnt compensate for its size, and i lose the texture size too. my level has a large body of water around a land mass, kinda like a floating island. the water itself is a map entity with the water action so my model can swim underwater, but the surface looks terrible, thats why i wanted to use a water shader for the right surface effect. my card is an nvidia geforce 6200 A-LE.
