tbh you have already mentioned a lot, and that's it's a laptop with dual chips for vga, you need to force the game to use just one, in settings, which is easy, but also a pain on some laptops as well, some work, others don't, so it's look of the draw, as onboard vga chips sometimes don't support DRx9 c fully, while the other will will, but getting the laptop to always use one, that's another thing
