I have an i7 Surface Pro 3 (8gb 256 HDD). So far it's the only computer I've playing ED on, hooked up to my projector. All it has really done is make me want to build a cheap gaming computer (or get an Alienware Alpha).
If there was a way to have an external GPU, I think this game would scream on here, but the GPU sucks as-is. I run everything at low at 1280x768 and I get between 10-30 fps. I even ran in 3D on my 3D projector but the method it uses (while not causing much slow down) is really blurry, you'd need to run at 1080p or probably higher, which the SP3 just can't do.
