V. 1.4.0 doesn't recognize nVidia card that works with 1.3.2

[amoroso]

As a temporary solution to the inability of compiling Celestia 1.4.1 on my Slackware Linux 10.0 system, I have installed 1.4.0 with KDE support. It mostly works, but performance on my nVidia GeForce FX 5600 Ultra with 256 M of RAM is worse than Celestia 1.3.2 with GTK on the same system.

I configured Celestia 1.4.0 with:

Code: Select all

--prefix=/usr/local/celestia-1.4.0 --with-kde --with-lua=/usr/local/lua


This version apparently doesn't properly recognize che card. The OpenGL info command does show the card:

Code: Select all

Vendor : NVIDIA Corporation
Renderer : GeForce FX 5600/AGP/SSE2
Version : 1.2 (1.5.3 NVIDIA 71.74)
Max simultaneous textures: 4
Max texture size: 4096

But the only available renderpaths are Basic and Multitexture, while Celestia 1.3.2 provides more such as nVidia GeForce FX, NVIDIA combiners, etc. And there is the performance degradation.

How can I diagnose this performance issue? How can I tell whether Celestia 1.4.0 is properly recognizing and using my card? Can I force its use via configuration options or other ways?
