Well, I ran the experiement...
1.) it does work, though apparently the FBO texture ends up upside
down with relation to all my other textures, so I had to do a little
correction for that
2.) it does increase the frame rate, but not substantially
3.) it does look worse (a 256x256 FBO is not too awf
I have a followup question, of course...
So, I am successfully rendering my scene to an FBO-texture, then using
that texture on a Quad in the background (so GPU renders to FBO
dimensions, and quad stretches it to screen dimensions). And it
works.
So, I thought, perhaps the OES drawTex function w
Fill rate does seem to be the biggest issue with performance. I would
make sure you have stuff like blending off to make the quad go as fast
as it can.
