nVIDIA drivers slow?

[richardve]

I've noticed that the nVIDIA drivers for Linux (latest) are almost 6 times slower than my windows drivers (12.01)
I'm very sure that it's NOT software rendering and the drivers are loaded correctly.

Can someone tell me if it's normal that those drivers are so slow?

I've read that it can be slower because of some conflicting Mesa drivers but since I'm very new to Linux I don't know wich files to remove...
Here are the mesa files I found in "/usr/X11R6/lib":

libMesaGL.so.1
libMesaGL.so.1.0
libMesaGL.so.3
libMesaGLU.so
libMesaGLU.so.1
libMesaGLU.so.3


Some details:

- Direct rendering is enabled.
- I've got XFree86 4.0.3 installed so that shouldn't be the problem.
- My videocard is a GeForce2 MX

Hmm, it seems that it's not a conflicting Mesa library...
(checked with ldd)

AGP is also enabled
(checked with cat /proc/nv/card0)

Don't GeForece's (and all NVidia cards) use the NVidia drivers and not mesa?

Well, actually I am using the nVIDIA drivers, but they're just 6 times slower than the windows drivers
And it's not software rendering (I've tried the Mesa drivers before installing nVIDIA's drivers)

Are you sure the files you posted above are the only opengl libraries you have installed?Try find / -name 'lib*GL*' as root to see if there are any other libraries that may be used instead of nvidia's.

[richardve]

This is what I got after doing that find command as root:

/usr/lib/libGL.so.1.0.769
/usr/lib/libGLcore.so.1.0.769
/usr/lib/libGLcore.so.1
/usr/lib/libGL.so.1
/usr/lib/libGL.so
/usr/X11R6/lib/libGLU.so.1
/usr/X11R6/lib/libGLU.so.1.2.030401
/usr/X11R6/lib/libGLU.so.3
/usr/X11R6/lib/libMesaGLU.so.1
/usr/X11R6/lib/libMesaGLU.so.3
/usr/X11R6/lib/libGL.so.1
/usr/X11R6/lib/libGL.so.3
/usr/X11R6/lib/libGL.so
/usr/X11R6/lib/libGLw.a
/usr/X11R6/lib/libGL.so.1.0
/usr/X11R6/lib/libGL.so.1.2.030401
/usr/X11R6/lib/libGLwrapper.so.0.1.4
/usr/X11R6/lib/libMesaGL.so.1
/usr/X11R6/lib/libMesaGL.so.1.0
/usr/X11R6/lib/libMesaGL.so.3
/usr/X11R6/lib/libGL.la
/usr/X11R6/lib/libGLU.la
/usr/X11R6/lib/libGLU.so
/usr/X11R6/lib/libMesaGLU.so

But like I said in my first post; I really don't know wich of those files can be deleted...

Hi,

try this:
rm -f /usr/lib/libGL.*
rm -f /usr/lib/libGLcore*
rm -f /usr/X11R6/lib/libGLU*
rm -f /usr/X11R6/lib/libMesa*
rm -f /usr/X11R6/lib/libGL*

rm -f /usr/X11R6/lib/extensions/libglx*
rm -f /usr/X11R6/lib/extensions/libGL*

rm -f /usr/X11R6/lib/modules/drivers/nvdia.o (or nv.o)
(not sure, about the path; do a search)...

then, download the NVIDIA_KERNEL and GLX thingy from their page, unpack it in your locar dir, and move the libs (with links)
to /usr/X11R6/lib...

the libGLcore* and libglx* stuff goes to /usr/X11R6/lib/extensions

the nv.o (or was it nvidia.o) has to be copied to /usr/X11R6/lib/modules/drivers/

in general: all files which contain "mesa"
have to be removed

that should work,

[richardve]

I've done everything wich is suggested but it's still too slow

[Walantis]

Hi,

another idea...take a look (as root) at this:

cat /proc/nv/card0

and tell me what you see...maybe there's a problem
with agp support ?!

hope it helps,

walantis

Nothing wrong with it AFAIK...

Could it be that Linux has a larger function calling overhead wich makes it slower when using immediate mode (glVertex3f[v], etc) for rendering?
