Very bad perfomances with nvidia driver

Hi all !
I've recently installed a LFS 6.0-testing and then added some grpahical components like Xorg 6.8.1, gtk... for example.
Then I decide to install Nvidia drivers (version 1.0-6111)
The GUI installer works well without difficulties and then I could modprobe nvidia module with no problem

However, when i look at glxgears, it seems there is a serious problem : 2500 FPS (in a normal situation it's about 6500 FPS ) 

i can launch a game like enemy territory but it's quite slow and textures are very crappy

i've read the readme file and try that : ldd /usr/X11R6/bin/glxgears
here is the ouput on my LFS system : 

        linux-gate.so.1 =>  (0xffffe000)
        libGL.so.1 => /lib/libGL.so.1 (0x40020000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x400a2000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x400b0000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x4017c000)
        libm.so.6 => /lib/libm.so.6 (0x4018e000)
        libc.so.6 => /lib/libc.so.6 (0x401b1000)
        libXxf86vm.so.1 => /usr/X11R6/lib/libXxf86vm.so.1 (0x402c7000)
        libdl.so.2 => /lib/libdl.so.2 (0x402cd000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

and now here is the ouput on my former gentoo system : 

	      linux-gate.so.1 =>  (0xffffe000)
        libGL.so.1 => /usr/lib/opengl/nvidia/lib/libGL.so.1 (0x40027000)
        libXp.so.6 => /usr/X11R6/lib/libXp.so.6 (0x4008f000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40097000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x400a5000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x40170000)
        libm.so.6 => /lib/libm.so.6 (0x40181000)
        libc.so.6 => /lib/libc.so.6 (0x401a4000)
        libGLcore.so.1 => /usr/lib/opengl/nvidia/lib/libGLcore.so.1 (0x402b6000)
        libnvidia-tls.so.1 => /usr/lib/opengl/nvidia/lib/tls/libnvidia-tls.so.1 (0x4098e000)
        libdl.so.2 => /lib/libdl.so.2 (0x40990000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

the files libGLcore.so.1 and libnvidia-tls.so.1 exist on my system, but i don't know why they're not here
in fact it's the first time that i encounter nvidia problems like that
Has someone any idea ?

Thanks in advance,
Antoine
