Minecraft single player FPS problems?

When I play in single player with the Serious Raytracing shader I somehow only get 30-40fps. If I'm on a server like eg. I have grief games at 100-130 fps. What could be the reason? It's not the world either. I created new worlds to test it out.

Can be because of the Wi-Fi if there's too veil geddost

Doesn't really make much sense to my knowledge. Why should the single player not work but the multiplayer?
