Is it normal to only be able to use shaders by activating a GLSL preset?

Hi.

Sorry if the question sounds strange, but the what is the normal way to activate a shader?

I’m only able to activate a shader by selecting a GLSL preset. GG presets doesn’t work either.

Thanks and sorry for my English.

I answered in the shader subforum. Please don’t crosspost.

Locking this one.
