I'm sorry, but since you don't even know the difference between RAM and vRAM, I am having a hard time to place my trust in your expertise this case. On top of that you are promoting a 2000+ dollar business tablet as a gaming laptop. Also, you haven't provided a response to my request for you to show off your great results of running EU on the Surface Pro 4. I am still waiting for that. I am not saying you are wrong, I never did, I am just saying that at least I have tried it and it didn't work because the game says "not enough vRAM", which clearly indicates that there's not enough allocate-able video memory in the hardware. I am very curious to know how you got around that error.
Finally, the link you provided shows me no successful test of running EU on Surface Pro 4. As I have mentioned to you before, I too have managed to get some games to work on Surface Pro 4, with very poor results, usually running at low-medium settings at 20-30 FPS, which is barley playable. And that is for the games that actually do start, as I have several games that doesn't start at all because of the low vRAM.
