problem - slow framerate - 1 frame per several seconds

[Crab]

Compiled from today's svn on Debian GNU/Linux (it is first time I do so - no previous versions), 1 x 2.0 GHz CPU, 2Gb Memory, nVidia GeForce FX Go5200
(https://ufoai.svn.sourceforge.net/svnroot/ufoai/ufoai/trunk, Revision: 13167 )

Graphics (framerate) is very slow (everywhere - on load, in main menu, in geoscape. In geoscape, I can see that time goes normally (so it seems that the game itself doesn't lag), but the framerate is very,very slow - 1 frame per several seconds). CPU usage is also ~100%.
It happens both in fullscreen mode and in windowed mode.
console log is here: http://www.terraninfo.net/me/ufoconsole1.log

UPD: searched about it on this forum, tried what was written there - "+set snd_init 0" doesn't help.

What can I try to do ? Is it a a graphics driver problem ?

please type "glxinfo | grep direct" to a xterm and post the output - it should be yes (direct rendering activated). otherwise you don't have your drivers set up correctly.

thanks for the hint!
 a google search of these error messages pointed that it is indeed the problem with the video drivers. I'll try to solve them
