Might just be a bad download. I play 0.96 on a fairly low-spec machine, 2010-vintage hardware, 3GHz Core(TM)2 Duo, GeForce GT 430 (entry level card when released!), I added a some RAM (up to 8GB) and went with an SSD to run W10. Don't expect a mobo video card to handle games like this, but as you see, the external card doesn't have to be super good.
