Sorry dude but when people search for Performance Shaders for low end devices they mean ones that look okay and that can give you at least 20+ fps on their computer. For most shaders the simplest test is to get at least a constant 200+ fps on normal mc without optifine. but some people dont get even 100. So they look for a shader that gives them okay performance on their bad computer.
But your shader does look incredible and I know that if you spend more time on it then you can make it run faster.
