Tip:
Try to make your graphics of a size close to something of a power-of-two. It will waste less precious memory.
A power of two size is one of the following: 8,16,32,64,128,256,512,1024
Images less than 8x8 pixels will be stored in a 8x8 texture as they cannot be smaller than that.
You can easily use different sizes for your width and height, they don't have to be equal.
Hi, where can I find more information about this? And would this be a good practice even when making games for the PC?
Edit: What I really want to know is how this helps to use less memory.
