I'am currently working on loading scene data(vertexes and faces) for a mobile game,my first thought was to load all data into system memory,and transfer only visible parts into video memory while traveling in scene.But when I learned mobile system memory and video memory share the same memory,I thought it maybe better to load all data into video memory directly,because no transferring is needed when traveling in the scene, Am I right?

It depends on the hardware.

 

On some systems there will be no difference. On most systems there will be a difference.

 

Generally if you've got vertex data, texture data, or similar data, that should live as objects in video memory if you will be using them for rendering.

I'am not familar with mobile programing,and never thought of putting all rendering data in video memory without system memory cache,thanks for your information, I will try to load scene data directly into video memor.
