Interlaced 3d rendering for Polarized 3d (nvidia or other driver)

[mycop]

As you know, the image on polarized TV is displayed interlaced. However, both frames for the right and left eyes are generated fully . Which consumes extra resources.
Question: Are there methods for rendering 3D frames, taking into account the peculiarities of output to polarization TV? Not necessarily NVIDIA.

Hello,
Be aware that if you want to use this method, you will need that the logical pixels perfectly match the physical pixels. It means that you have to use the exact native resolution from your TV, So:
-> On source side (computer) your game resolution must be TV native resolution and any scaling/overscan must be disabled in your graphic card's driver control panel.
-> On TV side everything about video picture (fluidity enhancement, zoom/overscan, film grain reducer etc) must be disabled. With some luck a PC mode or game mode may do that.
If you don't do that, lines will be melted and so you will have ghosting or even no visible separation between right and left eye.

For video/picture viewving, interlaced output are supported by software like sview (free, open source) or stereoscopic player (the more complete player).

for gaming:
With 3Dvision:
The easier way is to use 3Dfix manager in order to launch your games:
On the top right, choose the profile TV.
Then, go on settings -> display profiles -> TV profiles
Then tick and fulfill the form for "Link profile to display", "Display size", "3D display type", 3dmigoto 3D format", Game stings for 3D mode:-> "Game resolution".

If it still don't work, you can use an edid overhide, but do not use a pre-built one, because it may removes some capabilities instead:
Built your own using the CRU tool https://www.monitortests.com/forum/Thre ... tility-CRU: you just have to replace your TV ID by any 3D vision ready interlaced display, create and install the driver. At reboot, your TV will be reckognized as a 3d vision ready display using interlacing.

alternative to 3Dvision:
You can also use, an hacked version of tridef ignition or a rebuild version of iZ3D driver, but you won't have profiles and fixes for nowadays games.
They may come later for iZ3d as it is the only viable way for 3D gaming at long term.
