Sega Saturn emulator

Does anyone know how to get the Sega Saturn emulator to run smoothly? I have a pretty good laptop that should definitely run games, but it's always choppy. I've tried it on Wii, but that was just bad. After doing some research, I've read that an Nvidia Shield is great for emulation. However, before I drop $200, I wanted to know if anyone had any experience with Saturn emulation and knows how to run roms smoothly.
