Hello
Can someone point me to a guide or faq which cover most functions found
under "3d tab" and "Compatibity".
I'm most unsure about "32bit depth buffer", w-buffer, "alternate pixel" and
"Compressed texture".

What do they serve, and what is performance gain/lose.
 
Well, let's see...


"32bit depth buffer" is the z-buffer depth, which is the accuracy with which
3d depth is calculated - being better at 32bit then less, but slowing down
rendering.

"w-buffer" is a more exact, but less compatible - read "not transparent to
applications" - technology for 3d depth calculation.

"alternate pixel" has to do with how each pixel is output to the display
device, I've played with it and it makes the 3d graphics all wonky on my
monitor...

"compressed texture" is just that, textures are sent in their compressed
form to the video card and not decompressed first, saving considerably on
bandwidth between the system and graphics card memory...

z/w-buffers = more 3d accuracy, but some slowdown in rendering.

alternate pixel - leave it alone unless your picture is already wonky...

compressed texture = all gain with a card that supports it...
