| Too_Talls said: So what I want to know is, does it take more power to push 960 x 1080 over 792p? Is it all about the pixel count or..........what? |
Depends. The 792p resolution can use the built-in hardware upscaler to generate 1080p output.
960x1080 requires the software to blend the new image with the previous image to create the 1920x1080 final buffer. There probably is some kind of extra work going into it as otherwise you would see 2 distinct overlapping images while you're turning. You see some ghost images on screenshots but not entire structures or edges replicated, so there must be some algorithm analyzing the image to decide what to blend and what to interpolate. It's made me curious enough to give multiplayer a shot tonight, just to check out how their algorithm works. It's not a simple horizontal upscale like GT6's 1440x1080, can't be a complete blend either.
So yes, it probably takes more power in the form of an extra blending step.
Furthermore halving resolution far from guarantees double performance, that's what the article where this new resolution gate came from, is all about.

Going for an interlaced approach pretty much keeps everything the same apart from alternatively rendering the odd and even columns. The textures and draw distance still need to be up to par for a 1080p field of view. So it's even less of a performance gain than dropping down to 792p where you can dial back the level of detail.
