What are Low resolution soldiers on star wars battlefront 2 on psp

I have a PSP, so when it says Low Resolution, it's talking about the graphics. High Resolution soldiers show lots of details. A Low Resoluton soldier might only show his outfit, the basic form of a body, something that looks like a gun, and basic animation. I will say that I am not entirely sure because I've never played on Low Resolution, but if you've ever played a game on the computer and played 'safe mode' it's probably kind of like that.
