Forums - Gaming - Output resolution on the back of 360 game boxes different from ps3's.

EDIT: you can ignore me. Somehow I missed all of looney tunes posts.

Doesn't he X360 have a hardware video scaler and the PS3 doesn't?

that would explain a lot. The X360 doesn't take extra processing power to upscale the image to 1080p, while the PS3 doesn't upscale to 1080p since every developer would have to provide their own upscaler so they output in 720p since it takes less processing power and typically closer to native resolution.




If you drop a PS3 right on top of a Wii, it would definitely defeat it. Not so sure about the Xbox360. - mancandy

The PS3 scaler is a software one, I think. With a very wide array of tricks too.

  • For whatever reason, the Pure Video scaler in the G7x derived GPU (RSX) is gimped to horizontal scaling of specific front buffer resolutions. See B3D Article
  • As of the January 2007 PS3 SDK, only the following front buffer resolutions are supported for hardware scaling to 1920x1080p: 960x1080 1280x1080, 1440x1080 and 1600x1080
  • Games whose back buffers are rendered at strange resolutions must upscale the front buffer (at a cost of extra memory) to either 1280x720 (720p output) or to one of the acceptable 1080p resolutions. (Note: native resolution = back buffer resolution, front buffer = image for displaying/hardware scaling)


Yes it has limited hardware scaling

You are wrong.  Feylic is correct.  Ninja Gaiden Sigma WILL be upscaled to 1080p if you UNCHECK 720p as a display option.  Uncharted will do the same thing.  MS started adding the 1080p on the back of the boxes after Sony talked about native 1080p gaming for the PS3.

Only the native resolution matters for MOST HDTVs anyway.  The TV will upscale the image to it's native resolution. Example: If it's a 1080p TV, ALL signals are upscaled via the TV to 1080p.  The only people left out in the cold, from the console not upscaling, would be the people that were uninformed enough to buy a HD-Ready rear projection CRT TVs.

 

Uh, I suggest you go back and read what I wrote once more. I never said Sigma doesn't support 1080i/p, and I was talking about the PAL version of Uncharted which does not support 1080i/p in any way.

You do not want your TV to upscale the picture unless you're fond of input lag and shit image quality.

All HD CRT's manufactured before a certain date (as well as many newer sets) does not support 720p. Buying such a TV back when 720p didn't exist has nothing to do with being uninformed. Not to mention that HD CRT's still provide the best image quality money can buy, and the lightning fast response times make them especially well suited for gaming.

 

Um, I've played lots of games upscaled, and have had the same input response time, and amazing image quality.

A native 1080p tv getting fed a 720p signal will have more response time.  Its a fact, although it will be so small (maybe like 4 miliseconds) that you won't be able to tell.   Its up to what kind of tv you own, as goes for the upscaling quality on the tv

No. The PS3 scaler is hardware. The X360 doesn't have a hardware scaler. It's done by the GPU. MS made a statement saying ANA/HANA chip was the hardware scaler. Then, it was discovered that it was the GPU doing the scaling and ANA/HANA chip is just an output device.

Your information is correct. Scaling isn't important when the console can provide native resolution or your TV can scale it.
