nvidia card slow, clone mode the problem?
I've been trying to figure out just why my gfx card performance is so wretched, with latest nvidia drivers installed and am wondering if the fact I'm using the clone mode for TV-out is having a negative influence.
Is this type of configuration known to mess with gfx card speed and cause crashes when trying to use the card for any 3D purpose (games, google earth etc.)? Is there any way in Linux to set up an nVidia card so that only the video overlay surface is output to the TV, leaving the PC free for other use? Xorg.conf looks like this currently. Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig |
Hi try
Code:
glxgears mines a 7600GT so a 6200 should be at least 2000FPS if its working correctly. |
I get less than 600 with glxgears

You need to mention the distribution you are using and how you installed the Nvidia drivers. It makes a difference. As a point of reference, people often have much poorer performance if they use a "prebuilt" RPM (for example) than if they compile the drivers from source. The Nvidia site provides the information for this type of installation and it should go smoothly if you have the necessary packages to install regular programs from source.

do you still have a low score with TV out disable? either best download latest drivers from nvidia website |
I'm using Ubuntu, and have tried installing drivers in several different ways, but invariably from pre-built DEB files.
Switching off the TV-out mode doesn't seem to make a difference. |
If I backup and delete my xorg.conf, what command do I need to use to create a new one? xorg-xserve something?
|
running
nvidia-settings or reinstalling nvidia drivers will creat a new one or if you just start x as root startx it will automatically create a safe vesa conf file |
A word of caution on glxgears: the FPS "score" also depends on how big the window is that glxgears is running in. If you shrink it down to a tiny 1" or 2" square, you'll see much higher FPS scores than if you run it in full screen mode

I'm running it in a tiny window, about 50x50 pixels, the default size.
Should I have Load "v4l" in my xorg.conf or is that not necessary? |
