Lumen not working correctly

I can’t get Lumen to work correctly and I can’t figure out why. I’ve followed multiple tutorials now and have it set up correctly, but the lighting quality I’m getting is nowhere near on par with what I’m seeing elsewhere. I followed the he video linked below and at the timestamp, my setup is just black. From what I’ve read I don’t need an rtx card for software raytracing, but I am using a 1070 and an i7 5820k. Is my hardware the issue?
