half SBS vs full - I know it's less but can you tell the difference?

There is no difference if both files have the same size.
Also the only real full HD 3D is generated by Games using nVidia's GPU.
The 3D-Blu-Ray's 2D + Delta format is just a gimmick.
Frame compatible Side By Side will deliver the same quality or even better if compression ratios are the same or the file size are the same.

Why arn't 3D BR MVD encoded disks that pass the MVC decoding tests supply true 3D when decoded and output using the double buffer 1080p per eye HDMI 1.4a 3d format equal or better then instead of 720p per eye frame sequential/page flipping provided by the Nvidia 3D player?

I disagree with EVERY sentence you wrote here.
I have 3 BluRay3D movies, they're all stereo FullHD (or the cinemascope equivalent) I also have an ATI GPU and I play my games in FullHD 3D on my dual projectors
MPEG4 MVC's 2D+Delta is the real deal and is the most efficient stereo video compresison format to date, if you have a good encoder you will get better quality for the file size than anything else for stereo video.
There is a difference between full and half res side by side, and yes of course it is visible, but the obviousness depends on the quality of the down and upscaling performed as well as the video compression format.
Compression ratios can be used to compare image quality between a source and it's compressed file, but not between compressed files of different sources.
Different sources compressed with the same compression ratios will also have different quality thus cannot be used directly to compare
If both full res and half res files have the same file size, they have different picture quality
With modern encoders, the picture quality and compression ratios are not proportional, so unless you are using extremely low bitrates if the two files have the same file size, the full res picture will look better visually than the half res picture.

Please explain why 3D games played using Nvidia 3D vision are "true 3D" and movies filmed with IMAX 3D cameras and shown at an IMAX 3D theater maybe but if they are "true 3D and then enocded using MVC(2D+Delta) format on a blu-Ray disk they are not any more?

Simply, nVidia outputs 1920 x 1080 x 32bit color, 60 Hz
without any compression in-between the card and monitor.
Encoded movies have reduced resolution due to lossy compression, motion blurring and camera focus blurring.
Additionally 3D movies encoded using MVC 2D + Delta method have reduced texture specularities and reduced or totally removed low contrast details.

LoL icester,
Video games are not perfect sources, they have lots of shader approximations all over, blurry textures, reduced resolution (shadows and reflections), insufficient geometry details (obvious in close ups), insufficient rendering resolution (visible aliasing even with the best anti-aliasing modes enabled) in order to run the games in real time and most recent games even include motion blur and depth of field effects.
If the picture quality of 3D BluRays with MPEG4 MVC is insufficient for you then may I dare ask your opinion on 2D movies ?
2D BluRay (Mpeg4 AVC) ?
Digital cinema (jpeg2000) ?
Film ?

by 2014 every graphically, or just computationally intensive task will be run "on cloud" , this means limitless, supercomputer perfomance. Real time ray tracing will be commonplace very soon, streaming thru web browsers.
The console driven "prevgenHD" era is about to end. Now lets hope for MEMS displays.

Do you consider programs "filmed" with 3D IMAX cameras and shown at 3D IMAX theaters as "true 3D" or as just a "gimmick"?
Doesn't your statement that "MVC 2D + Delta method have reduced texture specularities and reduced or totally removed low contrast details" depend on the quality of the MVC encoder or is true of all MVC encoders as you imply?

Since it's inception in 1971 IMAX totally relied on gimmick
that is an adrenaline WOW effect on viewers due to gigantism of scenes and actors in every movie.
It goes for both in 2D and 3D movies. Additionally IMAX productions of 3D movies are no different than competition and it also uses parallax limit driven stereoscopic content distortion techniques which yield totally unrealistic immersion.
Again MVC 2D + Delta technique was originally created in Germany's Fraunhofer Institute.
http://www.hhi.fraunhofer.de/en/depa...sing/overview/
The intention was to create efficient 3D Television signal compression method. It was established that in order to satisfy limited bandwidth compromises such as stereoscopic detail reduction had to be implemented.
The creators also acknowledge that the methods creates 3D artifacts that are not present in original content.
For those who would like to test the MVC codec and it's 3D implementation, here is the source code:

That is nothing to do with Nvidia's GPU performance and it is only dependent on Game design.
4k textures can be used in rendering of FULL 3D HD format
without any compression between the card and display monitor.
Blue Ray has no magic capabilities and it is not capable of streaming real full HD content in 2D and much less in 3D.
