[SOLVED] Need help to improve my shader code

@pspeed

Maybe you could just look up the noise offset once.

Changed this as you said so it reads noise just once now.

@Ali_RS

I will look into detailed profiler results.

Some detailed profiler info (note vsync is disabled)

Without noise map:

With noise map but without below code from my other post:

float s = smoothstep(0.0, 1.0, noise.g) * 0.25;
diffuseColor.rgb = pow(diffuseColor.rgb, vec3(0.9 + s));

It looks like the effect of pow() is negligible.

I am ok with this if it is just my 2010 GPU chip, I suppose it should be fine on today’s gaming GPU beasts!
