I recently noticed that Grand Theft Auto wasn’t displaying at its promised 1080p (well, at least for the map and HUD and certain elements, as most of the game is actually, I believe, in 480p). I found that in order to get it to display in 1080p and not in 720p I had to go to Display Settings in the XMB and disable 720p and 1080i (you can’t disable 480p), and then the game ran at 1080p.
Hope this helps somebody out. Happy gaming!
Do you have to re-enable 720p if you play a game that supports that resolution but not 1080p?
Indeed, you have to re-enable 720p. The 720p game *will* play in 1080p but the graphics will be choppy if you force it to run in 1080p. Good luck, bro!
