I have very similar (old) hardware to you and the exact same problems. I'm pretty sure it's the hardware's inability to keep up with the video processing. If I use my work laptop or phone I have no issues. I agree it "didn't always seem to be this crappy," but I have no idea what may have changed with either the quality or compression these days. Of course, IANACN, so if anyone *is* a computer nerd and has a quick fix, that would be great. I just assume I need to buy something newer.
