Is OpenGL required ?

[Jack_Trowell]

From one of the hints during turn hosting, there was mention (if i recall correctly) of a "-x" switch to use when playing dominions 3 with old graphic cards, it might be what you need.

Someone with the manual (i'm still playing only the demo while waiting the game to ship) might be more precise.

Code:

---

******* Video Options *******

-w  --window        Run Dominions 3 in a window

-u  --fullscreen    Use the entire screen

    --bitplanes X   Try to use a color depth of X bits per pixel

    --zbuffer X     Try to use a depth buffer of X bits per pixel (default=16)

-T  --textonly      Use this with --tcpserver to get graphicless server

    --gamma X       Set gamma function (brightness) 0.1 - 5.0 (default=1.0)

    --opacity X     Set gui opacity 0 - 100

-r  --res X Y       Set screen resolution / window size (default=800 600)

    --animback      Use animated backgrounds

-a  --noanimback    Don't use animated backgrounds

    --fade          Use fade effects

-f  --nofade        No fade effects

    --nopopups      No helpful popups

    --fps X         Aim for this nbr of frames per second (default=20)

    --maxfps X      Maximum nbr of frames per second (default=50)

    --filtering X   Quality of OpenGL filtering 0-3 (default=2)

    --maxtexsize X  Max texture size in pixels 32-4096 (default=unlimited)

    --treequal X    Tree quality 1-5 (default=3)

    --texqual X     Texture quality 1-5 (default=3)

    --nolightfx     No light effects in battles

    --partamount X  Max nbr of particles 0-8 (0=none, 4=default, 8=max)

    --nograss       Don't draw the grass

    --noarcade      Don't draw floating damage numbers

    --noglext       Don't use any OpenGL extensions

    --vsync         Enable vsync

-V  --novsync       Disable vsync

    --renderpath X  Use different optimizations 0-1 (0=good for low mem cards)

-x  --fastgrx       Faster graphics (use 3 times for best performance (-xxx))

-p  --perftest      Run a performance test and exit

Arrrgh, I can't get Mesa to work. How did you do it ? The trouble is I can't find any sensible documentation, not to mention an example.
It would appear that I already had several 'mesa' packages installed, but I can't figure out how to use it instead of nv or nvidia. You know, the Driver "nv" section in xorg.conf . What do I put into xorg.conf (if anything ?)
In any case, glxgears doesn't run because;
Code:

---

b0rsuk@dziupla:~$ glxgears

Xlib:  extension "GLX" missing on display ":0.0".

Error: couldn't get an RGB, Double-buffered visual

---

I use (K)Ubuntu 6.06. I can't find anything except several dozen "ATI drivers suck and how to get rid of mesa" type of threads. Please help, I finally found a way to pay for Dominions3, and it would utterly suck to fail so close to my goal.

Basically, all calls to 3D graphics eventually end up in the glx library. Mesa's libglx will do the low-level calculations itself, while the libglx that comes with NVidia drivers or similar basically acts as a front end to your graphic card.

You need to replace the installed libglx files on your system with Mesa's variant, or set your loadpath (LD_LIBRARY_PATH, I think, but not sure) so that Mesa's libglx library is loaded instead of your video driver's libglx.

But... but.. but that sounds like work ! Oh well...

[B0rsuk]

Are you sure you meant mesa and not vesa ?

I tried Kubuntu 6.06 livec/install, and in 'safe graphics' mode it has 'vesa' in xorg.conf . And the funny thing is, glxgears works.

I copied both xorg.conf and lsmod output from livecd for further analysis, but no matter what I do I can't reproduce the effect. (jerky, but spinning glxgears on vesa drivers). Any ideas how to get it to work ?
I already found someone with spare Geforce2MX, but if I could manage without buying it, even for 'symbolic' price...

* nvidea, vesa, nv <--- 2D video drivers. They are completely unrelated to 3D (I suspect in some distant future they will become obsolete, too)
* mesa, fglrx, nvidia <--- 3D opengl libraries/drivers. I have no doubt there is some Debian command to switch to the mesa lib, try google
