// 3d commands are issued through the fifo. The gpu draws to the 2MB EFB.
|

// The efb can be copied back into ram in two forms: as textures or as XFB.
|
||||
// The XFB is the region in RAM that the VI chip scans out to the television.
|
||||
// So, after all rendering to EFB is done, the image is copied into one of two XFBs in RAM.
|
||||
// Next frame, that one is scanned out and the other one gets the copy. = double buffering.
