Also it doesn't work for some games where our GPU power isn't enough.
True 480p would require one additional GPU renderer or 100% faster GPu rendering, but we only have about 60% more GPU power, so it's not fast enough for all games.
Some games like this racing game use a squashed resolution to be able to fit 2 framebuffers in VRAM to run at 30fps in interlaced mode(15 full images per second only).
The current Bob implementation cannot handle that, neither can the 480p hack.
A small number of older High Definition television sets found in the
United States only have 1080i inputs for HD signals. Those televisions will currently only play some PS3 titles at 480p resolution. PS3 games render images at either 720p or 1080p for High Definition, and you need
720p input on the TV to play select games that do not support 1080p.
This is an issue on the side of the individual television sets, which do not accept 720p input, so when a game outputs an HD signal only at
720p, these select TVs have to display the game at 480p instead.
You can also do document and spreadsheet work (using Libre Office) and light image editing (using GIMP.) This all sounds great but the board cannot handle full-screen video playback from YouTube, unbelievably, even when you turn the resolution all the way down to 480p.
