This technique is use for iOS application. However, this theory of use power of two size of image is worth for PC application?

If you use HWA then using sprites with sizes that are powers of two does indeed help performance. There should not be much of any effect on Software mode ;)

Thanks LB.
The HWA runtime will lower performance if use the size of image isn't power of two?

No, you won't get lower performance than software mode. There will still be a performance gain, though just not nearly as much.

Thanks.

Thanks LB for info. But the object houkd be power of 2 in both directions equal or can be diffrent? Like 2x2 for platform or 2x256?

Also if I would like to have my character smaller than 64x64 if I make it 60x55 but in sprite size 64x64 would I still gain performance?

1. They can be different
2. I think you don't need to fit these sizes exactly, it's more about saving resources by carefully planning the dimensions of your objects. For a 60x55 and a 64x64 sprite MMF will need the same amount of memory because both are in the same range of power of two (above 32 and below/equal 64). For a size of 65x64 MMF will need as much memory as for a 128x64 sprite, because the first value is above 64 and the next power of two is 128.

Please correct me if my interpretation is wrong.
