Owners of a new Sony PS3 which has a built in Blu ray player will be limited to 720p resolution and not 1080p HD.
Although the PS3 is described as being capable of presenting games in 1080p, Sony’s Simon Benson said during a 3D demo at the Sony Developer Conference last week that their guidelines prohibit 3D games from being portrayed in the highest resolution, as it wouldn’t allow for a smooth 60-frames-per-second (via Joystiq). This means that even games that run natively in 1080p (like Super Stardust HD) will still be locked in at 720p in 3D.
Benson admitted to iUp.com that a “more cinematic game” might actually benefit from a lower frame-rate and higher resolution, but he said the Sony guidelines don’t allow for it. He also assured that even trained computer graphics artists could barely see a difference between a 720p and 1080p image in a 3D game, so it’s unlikely many regular consumers will notice.
