I thought you had to
use some specific Sony Dev Kit resolution (like 960x1080) to get the 1080 outputs...
first of all, to correct myself, i think software scaling is done through RSX/Cell, so its pretty much the same thing.
everyone told us it was impossible because we were under the impression that the 360 had a dedicated scaler chip whereas the PS3 did not, but really, the 360 does its scaling through Xenos. the PS3 on the other hand, actually does have a dedicated scaler chip, but for whatever reason, Sony is limiting it to horizontal scaling only for developers. no one (except for Sony and developers of course) knows if its actually limited or Sony is preventing developers from using both vertical and horizontal scaling. it doesn't make sense for Sony to limit the scaler chip, so it seems like its limited to horizontal scaling only. the scaler chip can take 960, 1280 or 1600 and upscale it to 1920(x1080), but like i said before, only a small handful of games use this method.
it seems like most developers are doing something similar to what the 360 is doing and using RSX/Cell to upscale. doing so, i think they can take any resolutions and upscale it to 720p or 1080i/p. and like i said before, many ps3 games are slightly higher or lower than 720p and upscaled through RSX/Cell.
