NoBodysGamer - I am not running 720P, and I can tell the difference (Killzone 3 is 720P, with its text artifacting and reduced resolution from its 2D mode). Please look at the pictures and complete discussion. Look at the smoothness of the text in the Dead Space 3D menus.
I am surprised that can see no difference between 1080P 2D/60 Hz and 1080P Checkerboard (I assume 3D)/60 Hz. For example, do any text artifacts appear at any point during your gaming?
I hope someone else actually TESTS this configuration, ideally with some type of instrumentation. Note that this test configuation will need to be a high performance configuration, with a 6950, 6970, or 6990 AMD card. I left a comment on the Tomshardware site - perhaps someone at this site will provide more insight.
Killzone 3 is 720P in 2D and "virtual" 720P in 3D
But in 3D its actually HALF 720P resolution and then its stretched to 720P
There are no artifacts in checkerboard and it looks just like the 2D.
Dont you have an INFO button on your TV? press it, it will show you if its 1080P/24Hz 3D or 1080p/60Hz 3D
My samsung does this, just press the info button button
