Is there currently a list of what shaders work with what devices or is it basically just trial and error?
In specific I was hoping the decal shader would work. But would like to know about others as well.
Thanks,
Theoretically they either work or don’t work depending on the hardware level being OpenGL ES 2.0 or not.
But performance differs massively (several times faster or not) and depending on the OS / update its running on there are performance deltas.
so yeah experience and trial error
Also most of the inbuilt shaders have a fallback for Opengl 1.1 so they will always run, its just a question of what still runs on the fallback. (the graphics emulation gives you a general idea on how it will look)
as for decal shader: do you use the shader or projector? if the later is the case I would recommend to readup all the threads here on as it has major performance impacts
