What determines the graphics of a device?
The major hardware elements that determine what graphics quality you can choose are:

Graphics chip built into your main CPU. The faster it is and the more parallel computation cores it has the more calculations per second can be done
The maximum RAM of your device
The display resolution. The higher the resolution the more pixel have to be calculated -&gt; the longer the calculation of each display frame takes -&gt; the less frames per second can be displayed
