    That "feature" is just because the hardware is not up to the task. This is why the iphone5 has so much GPU performance. Games have always taken more GPU than CPU. Since we are still behind the current top end hardware specs windows phone still needs to do these scaling tricks.

    As long as MS continues to use the Qualcomm SoC's, they'll always be stuck with whatever Qualcomm has for their GPU's. They've ALWAYS been weak in the GPU part. Their CPU core is top notch though, until the A15 ARM cores are released next year (Qualcomm's KRAIT CPU core is a kind of hybrid A7 or A9 part).
    Qualcomm uses its own Adreno225 GPU. Not a poor performer by any means, but its not the most powerful GPU out there. ANY phone using the S4 is going to have this GPU in it (like all the top end android handsets right now). And they have this SoC because of the integrated LTE capability. Their next gen GPU is the Adreno320, and thats coming out in some of the later dual core S4 parts and the quad core S4 parts.

    -Apple uses a PowerVR SGX 545 or something GPU...its pretty much THE most powerful GPU for smartphone/tablets.
    -Samsung's Exynos uses a MALI400 GPU i think. I BELIEVE this part is like ARM's A15 or whatever architecture where its kind of a licensed part that manufacturers can customize somehow.
    -nVidia's Tegra3 uses its own mobile geforce part. They know a thing or two about GPU performance since theyve forever been making PC GPUs under the geforce brand.

    nVidia is actually pure crap on mobile. Don't buy in to the Tegra hype.

    Yes, but this feature exists NOT JUST because the Adreno 225 isn't "up to the task" (no matter what your definition of "the task" may be). Even Apple's A6 GPU isn't guaranteed to be "up to the task" of rendering every iOS6 game at the iP5's native resolution. Weather or not the GPU is up to that task depends solely on how far developers want to go with their rendering algorithms, and how much the sum of them tax the GPU.

    Rendering at lower than native display resolutions has been a very common thing for quite some time. It is a technique used across all mobile operating systems. H3ll, even the cross-platform Unity graphics framework supports that feature, because the technique is just as popular on iOS where it allows developers to use the exact same rendering pipeline across a wide range of devices with varying native display resolutions and GPUs (iP3, iP4, iP4S and the new iPad). Keeping the same rendering pipeline means users can enjoy roughly the same visual experience on any of those devices (minus differences in rendering resolution). That is exactly the same thing this feature will do for WP8. Note however, that WP8 has a much smaller set of GPU's to support than iOS6, so for WP8 this feature really only abstracts away differences in native display resolution.

    At the end of the day, this feature is much more about software than about GPU performance. It's about relieving developers from having to deal with differences in hardware, which benefits consumers in the form of a consistently good user experience (or at least as good as intended) on any WP8 device.
