Very poor performance using kmod-nvidia

i have discovered that in certain games the supplied Kmod for nvidia leads to terrible performance issues for example games like tremulous built from source have a pathatic 17fps and dhlore has an fps of 5 which fluxuiates wildly. if i do not use the livia module and instead the nvidia installer then the performance is there and gone are some graphical glitches but it also brings it's own.

using the nvidia installer causes problems like glitchy bouncing icon appear (launching programs from kmenu) also there is a big bug present with all games in that they cannot scale up resolution to fill the screen (run a game at 640-480 and have the screen filled with picture) instead it appears uninterporterlated and hence unusable on a 1280-1024 monitor.

my question is what has been tweaked? I am perfectly happy using the kmod if they can tell me what was changed which 1) made it work correctly and 2) kills the performance of some games that have not been packaged by fedora community.

it is begining to irritate as i require a tremulous binary other than what was distrobuted and i am unable to use this since the patch does not exist to keep gameplay above 20fps

my graphics card is perfectly capable of this performance however.

fx5200 geforce
fedoracore 6

many thanks i hope you can help me resolve this issue soon!

You probably just need to play with the driver options.
Using the official installer in fedora is a bad idea.

yeah i realise that using official nvidia install does not work but very very poor fps in games isnt much better either. i think a certain render technology is disabled causing this problem since the fedora trem is a special patched build which the official build doesnt need

I totally agree...I wish I could find what was tweaked...I have spent hours googling...using the nvidia provided driver from the website made the desktop much more smooth --- for example, running xcompmgr and transset before running the nvidia installer was slow and choppy, now it is amazingly smooth and fast...but I get the glitchy bouncing icons from the panel as well...

I feel your pain

the real thing to watch is exactly what version of the actual nvidia driver you are getting when using the kmod.

You really need 96xx or 97xx.

then again, if you're really that worried about it, you wouldn't be using the kmod at all.

just get the 2 files yourself, both the nvidia drivers & the xorg-x11-nvidia to match.

If that's too much, which I doubt....

use the Add/Remove Software to search for the available "kmod-nvidia" packages in livna, then choose the right package yourself. When you run it through yum install you have a 60% chance of getting outdated, or incorrect, drivers. If you want aiglx to work, you need a 96xx or newer driver.

as far as the tweaks go, that seems to be a hard to find little bit of info.

little side note ---

it seems, at least for me, that on my Athlon XP 1.5 that the i586 arch runs better graphically than the i686 arch. I'm not sure why or how, it's just my observation. (and it's called a bug)

my 2 cents: clean out the console-installed proprietary driver;
go to and click on the link for installing the release repo under default/firefox on their webpage, and install per the instructions there. Use your Add/Remove Software, search for and install nvidia-drv-1.0-9755-2.i386.rpm, then edit your /etc/X11/xorg.conf to look something like this:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig

Note the load glx module, and the nvidia device driver. these MUST be in there verbatim, and highly recommend no lower than depth 24.
Luck! -O.

I will have to try the above post -- but I have posted on the nv message board many times, and googled for hours, I have a Dell XPS M1710, with a GeForce Go 9750 GTX card...and I can't find a proprietary driver that doesn't cause some unwanted side-effect -- the native nv works just fine, but of course doesn't have 3D effects, and what is the point with a 1Gb video card to not have 3D effects...I have found nvidia extremely unhelpful and unwarrantingly (if thats a word) condescending and cocky towards folks who try to resolve their own issues...when nv refuses to help

Anyway, sorry for the rant, had to let it out, I will try the above and let you all know how it goes for me

I still can't get desktop-effects to work in KDE either
