Check out a screenshot comparison of Borderlands 2 on PS Vita vs. Borderlands 2 on PC………..
Before you look at the comparison remember that the PC screenshot is most likely on high specification, and is much higher resolution than the PS Vita screen. The PS Vita screenshot will look a lot worse since it is blown out of proportion and will be much sharper on the actual PS Vita screen itself. So take these images with a grain of salt.
The PS Vita screenshot was taken from here and again remember that the PS Vita version will look MUCH better on the actual PS Vita screen.
