My hackintiosh is very laggy

I'm new to hackintosh and wanted to try it out. Everything worked but it was very slow my mouse was jumping and when I opend an app or youtube it lagged like hell I could not rellay on my mouse and needed to force close the app. I don't know why it was happening like that. Could anybody help me fix this?

My smbios was: iMac19,1

cpu: i7 9700 coffee lake
igpu: UHD Graphics 630
dgpu: nvida gforce rtx 2060
