No matter i stream or not,use x264 or nvenc，just enable preview always cause sudden frame drop.the frame drop is just a sudden,at first i wasnt realize it,i thought it was mouse lag.
It didnt happen before i bought my new main screen which is 2560x1440 240hz. My old set up was 1080p 144hz&900p 60hz,and my setup is 1440p 240hz &1080p 60hz(because my old 144hz screen can only reach 60hz with a cheap hdmi cable),my gaming setup is 3080,ryzen 5800x,16g ram 3600.
