Windows 10 app scaling question.

[Vapour_Trail]

So, since the Surface Pro 4 has just come out, I took the opportunity to buy a Pro 3 as they were heavily discounted. Of course, due to the high resolution screen, I use Windows 10's app scaling (set to 150%). However, what I want to know is if there's a way to set this for individual applications. Generally, this wouldn't be a problem, but there are certain applications (for example, old 2D games) that I use where their crisp pixelyness gets ruined by the upscaling. Is there any way around this? Also, on an interesting side note I have one application which is seems immune to the effects of scaling and runs at 100% (which for this particular application, is exactly what I want anyway).
