Hi, I ran glxinfo. Apparently Direct rendering is on. But gl library used is
still Mesa. Also, the Nvidia drivers are installed. I double checked it. I
don't get it. Why is the frame rate so slow? Here is the output of glxinfo:

Can you help me? If Nvidia drivers are installed, why do I need Mesa in the
first place? How do I direct FlightGear to use the Nvidia graphics library?
Thanks.
Ekhlas.

Sorry, AFAIK that means no acceleration.
The output from glxinfo (if you have it - it is not part of FlightGear)
is easier to parse - you only need to look at the first few lines:
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
If it says direct "rendering: No" you have no hardware acceleration.
For the NVIDIA driver go to
http://www.nvidia.com
and download the appropriate one for your card. It installs on top of
Mesa.
Your linux distribution might also have the NVIDIA driver as a package,
but mine (Debian) doesn't (or the version is too old).
For me the NVIDIA driver works fine - but I do need to reinstall it if my
package system updates the mesa package or if I change to a new kernel.
Cheers,
Anders
