1080p vs 720p upscaled rendering advantages

Of course there is. Scaling up means a loss in detail in texturing, shading (shadows, etc) and antialiasing.

 

asfaik you never want to upscale things. the loss in quality will vary, but there will be some.

 

ok, how about this one. I have a toshiba 42" that has a 720p native res, and supports up to 1080i. when i run my 360 in 720p it looks noticably better than running it in 1080i, however when i run it in 1080i its smooth as silk, but when in 720p, while it looks better, it seems to stutter a little bit. any ideas anyone? I would like to run in 720p, due to it looking better, but the stuttering is almost unbearable. what would be causing this? does anyone think that running through HDMI instead of the component cables would remedy this?

 

I'm not sure what you mean by stuttering, flicker is more noticeable on a progressive scan CRTs than interlaced but if you're on a digital display which I assume you are, flicker doesn't exist. Perhaps the games you're playing are dropping frames (caused by the higher bandwidth of 720p), but if this happens all the time, it's got to be your display. Can you take a picture or video of what's happening?

 

Its a digital display, a Toshiba 42HP66 plasma HDTV. Its not really a flickering problem, but more of what you were saying, like its dropping frames. I dont really have a camera to take a video, other than the cam on my laptop. When i get home from work i guess i could take a video with that, but i really cant guarantee if the video quality will be any good. as long as its enough to convery what im talking about i guess :icon_bigg I really do think it was what you were saying now, however. How could i fix it dropping fames if that is indeed what its doing?? and like i asked before, would running through HDMI remedy it??

EDIT: Also I have a HD-DVD player that I run in 720p that doesnt have the stuttering/dropping frames problem.

Dropped frames are the game's fault for being too demanding of the system, there isn't anything you can do about it unless they better optimize the game later on with a patch or something. I've Googled and it seems lots of games do have different frame rates at different resolutions, which sucks; I thought a selling point was that all games were natively rendered at 720p or 1080p and effortlessly scaled!

 

well i was messing around with my tv today and found a setting called "source" with 2 options: video and film. It was set on film so I switched it to video and it helped the problem a little bit. Its still there, but nowhere near as bad as before. I have noticed it happens more frequently on certain games than others.

 

skavenger, the problem in film mode might be juddler in 1080/24p playback.
