Haha yep i guessed that in my mind. Well i use the same and its an issue on the driver side of intel. Many of the features from shader graph dont work as well. So yeah many things from unreal that requires your gpu to render stuff wont work. I have an i9 10900k 32gb ram and no gpu so stuck with uhd graphics of intel. They totally suck. Your best bet is to wait for the rtx 4000 series.
