Can you be more specific about the particular Intel graphics card you have? If so, someone on the forum may be able to advise if the driver you have is actually the best one available - sometimes, even if Windows thinks it is the latest, Intel or the motherboard manufacturer may have a better one.
See [Howto] Where to find Hardware Graphics Info for your SketchUp forum profile (wiki) if you don’t see it directly.
Or, depending on your hardware (laptop, desktop?) you might be able to add a dedicated graphics card - ideally from the nVidia GeForce 10xx series - 1050, 1060 or 1070 aren’t too expensive, I understand, and cheaper than a new computer.
