Anyone have any experience of driving the tridef displays on the new passive stereo laptops?

Currently we support either side:side, top:bottom on external 3D TVs or Nvidia 3D using the directx hacks in these forums
For these screens can we just create a side:side display and have the tridef driver automatically handle the 3d?

I guess passive laptops use interlaced polarization, why don't you implement interlaced stereo rendering yourself ?

I can do that.

We didn't on external displays because it forces the graphics card to invalidate both the textures on each frame, doubling the load, but on a card with decent openGL alpha support it's do-able

I don't get why you would have texture cache problems, for interlaced rendering you just have to render the two views in off-screen buffers and then use a pixel shader to combine them into an interlaced image in the front buffer.

In a word Intel - in slightly more words, Intel's terrible openGL drives on all their laptop graphics chipsets!

Interlaced is no problem, if that's what the screens want I can do that .
