Beside the mandatory 3D frame packing formats, the Samsung HDMI 1.4 HDTVs also support a bunch of optional 3D mode, like interlaced, checkerboard and page flipping (called Frequency in the manual).

Best is, like with the 24Hz stereo the TV multi-flashes the frames to produce 120Hz, so no flicker at all.
You need the nVidia 3D vision emitter and a pre 260.xx driver to get access to the optional modes, as the new 260.xx drivers with beta 3DTV Play only offer the 2 frame packing modes 720p@60Hz and 1080p@24Hz when it detects a known HDMI 1.4 capable device (and only 3D bluray playback for unknown HDMI 1.4 devices).
Now you can use either "Generic checkerboard" for 1080p@60Hz checkerboard format or "Generic CRT" for 1080p@60Hz page flipping (= effective 30 FPS per eye) in the nvidia control panel stereoscopic settings. Please note that the nVidia 3D vision emitter is just used as a dongle to get access to the 3D settings, the HDTVs emitter and glasses must be used.
The HDTV does not switch automatically to 3D, you must manually switch to 3D and select the appropriate mode (Checkerboard or Frequency).
The checkerboard mode normally requires a sync signal from the the HDTV, otherwise a message overlay "No 3D sync signal" is shown. I got rid of this by a simple USB powered circuit that generates roughly a 60Hz rectangle signal (actually every frequeny above 10Hz did work) and feeds this by a mini stereo jack to the emitter. Since the nVidia emitter is not actually used to sync the glasses, the frequency doesn't matter.
For page flipping mode (= "Generic CRT" in nVidia control panel/ "Frequency" in Samsung 3D menu) this isn't required.
After trying a little I found the 1080p@60Hz checkerboard format to be my favorite, followed by the 1080p page flipping format. Still 60 Hz per eye is a big difference to 30 Hz per eye. But it really depends on the game type.
And yes, I can play Black Ops in perfect 3D now without the 3DTV Play beta frame packing bugs /blurry aiming sight or sky shadows of objects.
