Hi,
I have a Geforce 8400 GS. When using a window manager like KDE or fluxbox I find switching windows or tabs (like in firefox) rather slow. It might take like 300ms for a window to switch: it is not instantaneous as I would like it to be. Itś not really that annoying but I always strive for perfection  and I chose gentoo for its presumed performance so..
What I also find weird is the following:

Why does the glxgears score increase ? I was not doing anything special at the time.
Another strange thing is I lack the
agp directory in /proc/driver/nvidia
I do have this

I was suspecting I do not have AGP, but only PCI-express but why would nvidia use the agpgart module then ?
Some general information:
I have Dell Inspiron 1720 with a Intel Core 2 Duo.
I run linux 2.6.22-r8
If you require more information, I will be happy to supply it.
Best Regards,
Spetsnaz |

It's not - zero means False. |

a) you are using a 8400 - this beast is really, really slow.
b) if your glxgears fps increase it might be the CPU OR the GPU increasing its frequency (or both).
If your GPU is able to change its core/memory frequencies you might want to have a look at nvidia-settings and the README.
c) maybe your video is slow, because of incorrect/stupid mtrr - a common problem with intel based systems.
