Call this once:

function Test()

prog:Bind();

prog:SetVertexShaderParam3f("eyePos", 1, 1, 1);
prog:SetVertexShaderParam4f("texMove", 1, 1, 1, 1);
prog:SetSampler("frameBuffer", 6);
prog:SetSampler("normalMap", 1);
prog:SetSampler("distortionMap", 2);
prog:SetFragmentShaderParam1f("screenWidth", 800);
prog:SetFragmentShaderParam1f("screenHeight", 600);
prog:SetFragmentShaderParam1f("etaRatio", 0.1);

prog:Unbind();

end

Call this 10000 times

Test();
