Are GLSL shaders darker than Slang shaders?

Lately I have been testing various glsl shaders as well as slang and I have noticed that, for example, the cyclon shader? The glsl version is a little darker than the slang version

why does this happen?

I don’t know if there’s any actual difference, but I do know that some shaders have different glsl and slang versions, or even other defaults. So the shader you’re testing may be from an older version or just configured in another way.

Shaders have some differences in their code, defaults etc and that’s all. Slang is pretty much the same code as Glsl and should be identical as long as you do the same things. Slang has a little more perfomance in heavy shaders in my experience like 5% or so.
