NEWS UPDATE: I received this letter about the drivers for ATI cards and my demo. Hello Bobby, I can definately see the issue here and will submit a bug on this, thanks for letting us know. I've been able to narrow down the problem a little so hopefully the fix is pretty straightforward and should happen relatively quickly. I'm curious though about the sample as I received the original message followed by this second one. Both had attachments with the same name and size but I can't check the timestamp to see if there was any difference. Can you confirm that they are the same sample code? thanks, Jeff Royle ATI Developer Relations devrel@ati.com This is an major update. I redid the the stencil buffer draw routine. more like lesson 27. New Link Should work on ATI now... This time it's Carmack Reverse. Download Link w,s - move forward backwards. a,d - strafe i,j,k,l - move light1 arrows - rotate and down arrow stops numpad 4,5,6,8 - move model vertical and horizonal. I know it works on Nvidia cards, but if you have an ATI card(s) then feedback on the demo would be great.

With an oooolllld ATI (rage 128 pro) it simply crash (the instruction at "0x0000" referenced memory at "0x00000" The memory could not be "read")

two yellow points.
If vsync is off, then the light might have moved too quick and out of the ''box''.

Sphax: i don''t check for the VBO extension and just load it.
so, the buffer elements are NULL, referencing memory zero.
