I think he's proposing that the PS2 renders at 640 or 720 pixels across regardless of whether it's in 480p or 1080i mode, but the vertical resolution does increase slightly. 640x1080i would mean a 640x540 image rendered every 60th of a second, and 640x480p would mean a 640x480 image every 60th of a second. Less than 13% fillrate increase, so it's definately possible without lag. It's probably easier to do this than manually scale it.-tkf- said:Could you explain how this works?
How does a 640x960i scale to a 1920x1080i image within the PS2?
As for the horizontal scaling, that's not an issue at all. The info is transmitted to the TV in analog scanlines, so basically the TV is doing the scaling. It's just not getting a signal of as high frequency (1920 pix per line) as it could handle.
