does dolphin support quad core in 2022 (IDK what im doiiinggg)

[MKWII_FREAK]

I'm very new to dolphin, I downloaded it and when I went to play games the frames were extremely low and spikes all the time. I really don't know how to set up dolphin and I have pretty alright specs too and run like rocket league at max settings and still get 140+ frames. Idk how you can look at my specs, but I put them down when I signed up. I really don't know what I have to do.... PLZ HELP!!!!

thanks for your time
