Slow framerate in 3d

i286 · 12-28-2003, 06:27 AM

When I try to run a 3d application (tux racer for example) I get about 1 or lower frames per second.
I have Fedora core 1, AMD 1800+ and GeForce 4 with latest nVidia drivers. Should I enable hardware accerelation or something ?

Driver readme said that when running xdpyinfo extensions should have glx, nv-glx and nvidia-glx but I only have glx and nv-glx. Maybe that's the problem. What should I do??

get to a konsole and type glxinfo. look for a line in the output that says direct rendering: X, where X is Yes or No. if its No, then youre using software acceleration. if its yes... well, you get the idea.

Thanks for the reply.
Direct rendering is yes but still only 6.4fps on glxgears

i think i remember seeing a problem like yours in this faq:
http://icculus.org/lgfaq
its REALLY big, so look around alot.

Nope, couldn't find anything. Been searching the net for 8 hours now and getting a little tired. I don't want to go back to windows but if I can't get this work I have to.

Got this nv_check from the link file but it said my driver installation was ok. Totally out of ideas.

Ok I think it's the missing NVIDIA-GLX extension that does the problem. But what are these extensions exactly ? If anyone knows (and shares that information) I'd be really happy.

I think I'll post this to some other forum than games since it has very little to do with games and there aren't many readers on this section.

Sounds like you could be right about the NVIDIA-GLX extension. Edit /etc/X11/XF86Config-4 and change the section named "Module". Mine looks like this:

Code:

Section "Module"
    Load        "dbe"   # Double buffer extension
    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension
    EndSubSection
    Load        "type1"
    Load        "speedo"
    Load        "freetype"

# This loads the GLX module
# This is the section you will need to look at and possibly change/add to
    Load       "glx"

# This loads the DRI module
# You should have this already, since glxinfo said that direct rendering was enabled
    Load       "dri"
EndSection

Have a play. You probably have nv-glx loaded but you may need to add the line:

Code:

Load    "nvidia-glx"

or something similar.
When you've done that, restart the X server and it should (hopefully) work
Hope this helps

glxinfo for me:
direct rendering: No

How do I change this to yes?

You need the dri and glx modules loaded in the XF86Config-4 (see above). You also need the appropriate drivers enabled in your kernel. You will need DRI, and the driver that corresponds to your video card enabled.
