Hi! Sorry, but I fear I won’t be of help. Not only do I play the disc version of the game (I’m old school like this) but I also still play on Win7. As to what my specs are, I’m using an NVIDIA GeForce GTX 650, my processor’s an AMD quad core and I’ve got 8gb of RAM which is plenty to run the game on high settings.
Regarding your game troubles, I think I remember a thread on leefish (went around on tumblr) about how to make your game run on Win10 and another one about how to make the UC work. If you google it, it should come up.
As to how good my game looks: part of it is also the screenshot program I use. Don’t use the in-game camera if you want to take sharp pictures. I’m a big fan of Gadwin myself.
Of course, if any of my followers know how to solve Anons problem, shoot me a message!
