[Bug-gnubg] Concerning 3d, reply to archive message.

[Marco van Tol]

Hello all,

In the archives I noted an email from Jim Segrave where he mentiones a
colleague with a Matrox G550 graphics board, which has DRI support, but
won't get recoqnized by gnubg as an accelerated graphics board.

That colleague is me. :)

In the mean time, I tried the same thing at home, where I have a
Pentium 4 2.8Ghz with an nVidia 5600FX card with 256MB of graphics memory.

The gnubg performance test with that board without shadows or other options
ticked on is 74 frames per second. Needless to say the 3d experience is
fluent. :-)

The only things I noted are the following:
- gnubg also does not recoqnize this board as being graphics accelerated.
- I do have DRI support for this card. (I attached the output of glxinfo)
- The operating system I run this on is FreeBSD 5.1-RELEASE-p2.
- If I setup the game in 3d mode, with the default panels on the right, the
  screen gets _completely garbled_ when I disable/take away the last panel.
  Bits and pieces of a backgammon board are all over the screen. (Within the
  gnubg window however) :-)

Unfortunately, I don't have as much OpenGL programming experience as I would
like to, which makes it a bit hard for me to diagnose why gnubg does not
recoqnize the graphics board as 'hardware accelerated' myself. I intent to
assist in the matter though. ;-)

Please let me know if you want any more info.

Kind regards,

Marco

P.S. I am not the fastest replier on the planet, but I will keep an eye on
the list. :)
