What is frame rendering?

Alternate Frame Rendering (AFR) is a technique of graphics rendering in personal computers which combines the work output of two or more graphics processing units (GPU) for a single monitor, in order to improve image quality, or to accelerate the rendering performance.

What is GPU rendering on Android?

Graphics Processing Unit (GPU) is a co-processor that takes on graphical calculations and transformations so that the CPU(Central Processing Unit) does not have to be burdened by them. GPU Rendering is done to use 2D hardware acceleration in your Samsung device to improve graphic performance.

What is code rendering?
