Awhile ago I edited the shader to remove the grainy effect. For anyone interested in how its done, edit Data\Shaders\Filters\CompoundFilterPS.fx and replace
Code:
// noise
float4 noise=tex2D(customTex0,In.Tex0*float2(NoiseTileX,NoiseTileY)+rand.xy)-0.5;
C=C+noise*NoiseIntensity;
with
Code:
// noise
// float4 noise=tex2D(customTex0,In.Tex0*float2(NoiseTileX,NoiseTileY)+rand.xy)-0.5;
// C=C+noise*NoiseIntensity;
