Just wanted to say my Surface Book (first gen, Nvidia graphics, but not the performance base) with i5/8gb of ram plays the game @ about 30fps stable on Ultra-ish settings at ~900p, I dial back the settings a bit and use Cel shading though and its closer to 45fps in most areas, but I max the fps at 30 because I'd rather have a stable 30 than an up and down.
Ironically, my much more powerful iMac, doesn't even have the "advanced" graphics options available, can't figure that out at all... so no shadows, reflections, depth of field, etc
