What this implies is that if you are doing a more involved graphics project on the PS2, you will also need to use a (or make your own) VRAM texture manager, as the textures will get replaced all the time in VRAM during rendering. frame at 30 frames/sec, which over twice the size of the EE memory. You may think that that 4 MB of VRAM is not a lot, however keep in mind that the GS runs 150 MHZ and the bus is 128-bit wide, if you do the math you will see that it is in theory capable of transferring about 76 MB pr.
