Hi, i have some questions about nvidia graphics card drivers drivers majorly because im still kinda new to linux.

Firstly i would be interested what framerate you people get with glxgears, because imo... im getting low ones (about 1200fps and 3D games majorly lack fps).

Second of all, is NVAGP better, than kernel module AGPGART...
Point is, im concerned that my nvidia drivers arent configured correctly, ill post as much as information i can find out, maybe somebody is able to help:

distro is Debian sarge and gfx card is geforce 4 mx440 (4x agp).

fast write and sba seems to be enabled (checked in bios in case too) and host-bridge is supported by nvidia.

sba not being supported it quite a weird, if i turn fast writes off in bios sba gets magically enabled... thats ever weirder.
and must registers have different values?

go figure

so the agpgart is loaded, but is there way to unload it, and force NVAGP to be loaded?

nothing more useful there

Now im completely lost in those piles of information which are quite cryptic to me, seems like some drivers are enabled... but on the other hand having around 20fps in Neverwinter night with quit moderate settings simply screams that something must be wrong with my gfx card drivers (aye, i can run doom3 demo at same speed under windows...).
Could somebody please make this information little more clearer to me, and give suggestions what should i do.

[edit]
oh yeah, i dont know if thread is supposed to be here? hardware itself is alll fine, but drivers... hence... software... isnt, but if the location is wrong move it

hi,
just ignore glxgears -- it's pointless and is intended just to test gl is working.

but i have seen where on some systems the stock agp one works better so it's not really a big deal
in patricular i saw someone try on a via chipset and the stock agpgart one was a little better
make sure in x config
Option "RenderAccel" "On"

main suggestion is to turn color depth down to 16
DefaultDepth 16
makes run alot better and i can't tell the difference

i wouldn't worry about fast writes it doesn't seem to help

i think those error messages about NVRM: not using NVAGP, AGPGART is loaded!!
might mean your agpart is built into kernel instead of module
might need kernel rebuild
(although showing up in lsmod suggests it's getting loaded as a module doesn't it -- duhhhh)
check it's not getting loaded as an option in /etc/modules or something
or possibly you are using "framebuffer" on your console as a boot option and that loads it.
you could try onloading it with rmmod before startx
and i think the nvidia source needs a little hack to run at 4x on that chipset
at least they used to
if you want to give that a try but like i said most likely not worth the trouble
sh ./NVIDIA-Linux-x86-whatever.run -x ( it will extract the drivers)
cd NVIDIA-Linux-x86-whatever-pkg1/usr/src/nv/
edited "os-registry.c"
Modified theses lines:
static int NVreg_EnableVia4x = 1;
{ NULL, "ReqAGPRate", &NVreg_ReqAGPRate, 1 },
make install

Thanks for tips, adding RenderAccel seemed to help little (glxgears jumped to 1400 fps, tho' it might be some other factor what lowered fps speed before).
Ill do some research before using rmmod or recompiling nvidia drivers, i have painful experience doing stuff blindly with linux

what most interests me atm, is how to force agpgart not to be loaded.
