What determines the graphics of a device? I do play a lot of games and most games settings have options to either set your graphics to low, average or high. So I'm really curious to find out what exactly determines the graphics of a phone so that I can set my game graphics according to what will work perfect.
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
