I wonder if your computer has a setting for the "shared" RAM for the video card, to where you can direct more resource to the video display?... I'll try to get my Win8 laptop to fire up later today (its battery will no longer take a charge), and see what I can find in that. On this Win10 laptop, it shows an Intel HD Graphics 620 with 4035mb of shared RAM, with 4163mb available. I do not see anywhere in this to adjust those figures though. With one of my older Intel laptops (P4??), there was a little applet in Windows to adjust that figure for shared RAM, which helped immensely in it being able to run certain programs.
