Default nvidia driver linux performance slow

I am having poor user experience/performance using Mandriva Linux 2009.1 x86_64. My OS and Desktop computer hardware details are as follows:

OS: Linux Kernel 2.6.29.6
Processor: 64 bit AMD Processor
Video Card: NV34 [GeForce FX 5200]
NVidia driver: 173.14.18

The overall usability/responsiveness and font rendering is much inferior compared to laptop with built-in Intel video card running Windows XP 32 bit!

Please advice if it is the nvidia driver or any xorg.conf settings or anything else?

My xorg.conf snippet is as follows:

Section "Monitor"
Identifier "monitor1"
VendorName "Plug'n Play"
ModelName "VX2262wm"
HorizSync 24-83
VertRefresh 50-76
EndSection

Section "Device"
Identifier "device1"
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce FX series"
Driver "nvidia"
Option "DPMS"
Option "ShadowFB" "true"
Option "UseEdidDpi" "false"
Option "DynamicTwinView" "false"
Option "DPI" "96 x 96"
Option "AddARGBGLXVisuals"
# Option "PixmapCacheSize" "300000"
# Option "OnDemandVBlankInterrupts" "True"
EndSection

Section "Screen"
Identifier "screen1"
Device "device1"
Monitor "monitor1"
DefaultColorDepth 24

Subsection "Display"
Depth 24
Modes "1680x1050" "1600x1000" "1440x900" "1280x800"
EndSubsection
EndSection

A 5200FX is slow to begin with. Upgrade your graphics card.

Run glxinfo - look for direct rendering: yes

Actually, that's pretty pointless these days. You can have direct rendering with the Mesa software rasterizer. The thing to check is 'glxinfo | grep -i render'. That will show the direct rendering value, as well as the opengl renderer string.

The results for the commands suggested are:

direct rendering: Yes
OpenGL renderer string: GeForce FX 5200/PCI/SSE2
I had originally purchased this external card thinking that my Linux usability performance for years has been because of using the motherboard built-in Video. Using an external GPU with its own processor and memory may provide better performance. Even now, I have the option of using the NVidia Motherboard (GeForce6100SM-M) built-in video. Wonder how its performance will be in Linux.

Any other performance options that I could use within the xorg.conf file?

The onboard card should be faster because you can use a recent driver on it (185.xx or the current beta drivers), the 2D performance enhancements that started with 180.xx are not available in 173.xx drivers.
