I am experiencing graphics performance that is less than ideal, not terrible but there are lags and video isn't completely fluent. I have a GeForce 8400 GS on a 1920x1200 screen, and am using the proprietary 195.36.15 driver (64 bit system). Previously with Kubuntu 9.04 and older drivers there were certain commands like glyphcache that improved performance significantly. What are people's experiences for Lucid? I haven't modified the xorg.conf from what the automatic installer did. To be honest, I had hoped for improvements compared to Hardy, but it seems almost slower.

Re: Nvidia proprietary driver performance
I'm running both Kubuntu 10.04 and sidux (2.6.33-2 kernel) on the same hardware -- an Nvidia GTX260 on an Intel board with an X6800 CPU, with the 195.36.15 driver, 64-bit. I have a big Samsung SyncMaster 1100 CRT. I did a quick check with glxgears. At the moment, the frame rate is faster for the sidux system -- about 9,000 fps, versus around 8,000 for Kubuntu. But these things vary and it's not a pristine test (glxgears is not a good benchmarking tool either). I do not need to use any "tweaks". /etc/X11/xorg.conf looks like this:

Re: Nvidia proprietary driver performance
There are still several things you can add to xorg.conf if you want some better performance. You don't give any fps references, but mine are around 7600fps with glxgears (38000 per 5 secs): kubuntu 9.10 64bit, fully updated, 195.36.15 driver, 8800gt XFX Alpha Dog, overclocked to 705/1050, dual dell 19's via DVI.

Re: Nvidia proprietary driver performance
Thanks, I will try the options. BTW my glxgears is ONLY 400 per 5 secs, that is running it in fullscreen mode. The default window that pops up when starting it gives about 8000-9000 FPS. Firefox scrolling isn't very smooth, especially when running Openoffice with large presentations and lots of images.Comment

Also, you can run nvidia-settings as root, with Alt-F2 "kdesudo nvidia-settings" and click the "get EDID" button to have it query your monitor. Then, set the resolution, leave refresh set to "Auto", and click "Save to X Config File" and "OK" it. Then restart X and maybe it will do better.

Re: Nvidia proprietary driver performance
If the edid just won't work - you can set everything manually. Start by getting all your manufacturers specs.Comment

Re: Nvidia proprietary driver performance
Yes I had run nvidia-xconfig. Doing the EDID through the nvidia-settings added the line ' Option "metamodes" "1920x1200_60 +0+0"' to xorg.conf, but on starting the same EDID error shows up in the log file.
However, since I don't use the 1280x1024 mode but 1920x1200, isn't that error irrelevant? I'm amazed at the FPS you guys are getting, there just has to be something wrong!Comment

Re: Nvidia proprietary driver performance
I'm not familiar with the 8400 -- I did have an 8800GTS/320 for awhile and it was a very nice card. The GPU speed and onboard memory are important to your performance. The performance (speed) of your CPU also influences the graphics performance, so that needs to be considered. I assume you've already worked Google as much as you can to learn about any special settings for that card. You can try overclocking it with the coolbits option, but that won't make a huge difference.
As mentioned above, when leaving glxgears at the default window size, I'm getting ~44,000 per 5 seconds on Kubuntu 10.04, with Desktop Effects enabled, on a 1600x1200 screen. My x6800 CPU is overclocked to 3.45GHz, and my GTX260 is also overclocked to whatever nvidia-settings said was the safe limit.
Firefox and OOO are both graphics hogs, so it's not surprising that they will stress your card. 1920x1200 is a big screen -- I'd say you're probably getting about all that card has to give.Comment

Clock: 333.000 MHz
I run an Intel Quad Core overclocked to 3 Ghz.
Your graphics performance is 100x higher on a screen with a resolution that's just 20% lower! That is staggering... I know the 8400 is not very fast, but I have this feeling that it should be faster...
Overclock to GPU 579 / memory 505 gives at least 760 in glxgears.Comment

Re: Nvidia proprietary driver performance
I think you should be way faster than that. Have you tried booting to a livecd from another distro just to see?Comment
