Standard shader mobile?

Now I have a quick question about the standard shader, I have looked online but most threads are outdated.
As of now, how is performance on mobile? Is it much more expensive than a legacy bumped diffuse? Is it better to only use the standard shader on things that need it?

Thanks

 

I'm not one that works with mobile devices, but yes it would be. The standard shader incorporates numerous other things that the legacy diffuse does not; reflection, specularity, etc.

 

And both of those can, ironically, be disabled on a per material basis in Unity 5.4! (And most of the other stuff, like parallax and detail textures, are disabled by default for mobile.)

It'll still be slower though just because it is a more complex shader.

 

newer devices like galaxy alpha have no problem with the standard shader it ran 60 fps like its nothing, however older devices (like: galaxy note 2, galaxy express 2) had a very small performance impact (somewhere around 2 - 5 fps) so it's worth while trying out the standard shader.

I personally would switch to standard shader because it literary looks 10 times better while having a small performance drop.

Standard shader can look really ugly at times on OpenGL ES 2.0 devices so I would use a legacy shader for those devices or maybe look for somet costom pbr shader in the in the asset store, maybe there is something that will work around those that appear on OpenGL ES 2.0 devices using the standard shader.

 

Thanks everyone! I am targeting a Galaxy S3/Nexus 4 and newer, I'm still not sure the performance difference using legacy bumped specular, vs using reflections and specular on the standard shader, of course it is a more bloated shader, but is performance that much worse/noticeable especially on the 2013 + devices ?

 

I don't think that you should be worrying as much about performance as you should for how it will look on OpenGL 2.0 devices and I don't know how it looks on other devices but it look pretty crappy on note 2, so will need some kind of fallback probably for those devices if there is no alternative that works.

But for devices that support OpenGL 3.0 you can definitely use standard shader because most people won't even notice the performance difference.

I'd say you just make your game look as good as you can on OpenGL 3.0 devices and on OpenGL 2.0 you just take some legacy shader that works without showing any artifacts. I don't think you should really spend too much time on GL 2.0 devices, because that technology will be only history in next couple years.
