As a beginner(in GdxLib+Android), i found that for rendering particular screen, we can render that using both ways then when to use specific ones? & What is the best option for Updating the smaller part/region of the screen?
That being said, I asked for opinions on its real impact here, but since I've got no answer yet, I decided to give a try. It's working nice so far but if you can use a texture, I'd say to go with that. (I'm not using a texture because I'm writing a small library and don't want to include non code).
