In the V2,

Thomas told me that if we implement our own TTM-based memory manager,

we will also have the possibility of implementing a faster console.


Back to that time I do not even know the bandwidth of our hardware.

1) The bandwidth of copying buffer from the system RAM to system RAM;

2) The bandwidth of copying buffer from the system RAM to dedicated VRAM;

3) The bandwidth of copying buffer from the dedicated VRAM to system RAM;


We can make the right decision only when we know the various bandwidth 
listed as above.

How to implement it.
