Remove Film Grain effect from FNV Enhanced Shaders

[1uokuoruokuok]

i just recently installed the new version of the FNV Enhanced Shaders cinematic beta 2

which among the other effects it includes the film grain effect which i found annoying and problematically for me because it drops my FPS really bad so does anyone know how to correct remove the effect from this mod

The things i thought and did was :i gone to the effect.txt and removed these:

 

//grain noise

#ifdef ENOISE

float origgray=max(res.x, res.y);//dot(res.xyz, 0.333);

origgray=max(origgray, res.z);

coord.xy=IN.txcoord.xy*16.0 + frac(Timer.x * 400000.0 + Timer.x);

float4 cnoi=tex2Dlod(SamplerNoise, coord);

res=lerp(res, (cnoi.x+0.5)*res, NoiseAmount*saturate(1.0-origgray*0.5));

#endif

 

Is it the correct way,?is it bad? is it safe?
