Bad opengl performance with two or more OpenGL windows on nvidia drivers (GF 7600 GS)


Hello,
When I run one glxgears application,it shows about 5500 FPS.
When I run another window(s) their performance is very poor, far less than 5 FPS, while the first window mainain good performance about few thousands FPS.
I think that only the first instance of glxgears is using nvidia driver, while others use MesaGL. This is not glxgears problem, the same problem i have with two or more mplayer windows with "-vo gl2".

Below some data about software:
