Jagged line on meshes

Hey clockworkocean thanks for your reply. But I don’t want anti aliasing to be always on because it could impact fps and battery drain soon. From this documentation link text

What I learnt is reduce screen percentage and upscale it to higher resolution to get nicer look. I think this could solve my problem. But I don’t know how to upscale it to best fit my phone screen after reducing screen percentage through command. Please tell me what that means and how to do it. Your answer is very important to me as well as others. Thanks clockworkocean.
