Isn't 1600x900 better for playing with snap enabled? 1360x1080 needs to be scaled both ways.
Snapped game resolution is actually 1440x810, 1440x1080 would be best I guess.
For most games it doesn't matter anyway, so many post process blur effects nowadays that 900p or 1080p gets lost in the filters. Chromatic abhoration, motion smur, temporal ghosting, etc.
