About the number of texture to be used

The recent GPUs take time to switch textures used for drawing. So, if the frequency of switching textures to use is reduced, it happens to help improve working speed of application.


  • To reduce the number of textures used for one-time frame drawing of application.
  • To reduce the number of textures used within one animation (Not using textures per every parts).

For example, it is a good idea to prepare an allocation and a plan for the textures used for the drawing just like “collecting, into one piece, such textures for the Sprites that are utilized for the user interface of applications”.
