Poor выступление with Nvidia 540M and 352.63 драйвера on Ubuntu 14.04LTS

After I installed the драйверы and switched to the NVIDIA card the framerates I get on glmark2 пахал just absurd:

[shading] shading=blinn-phong-inf: FPS: 393 FrameTime: 2.545 ms

The same тесты with the default драйверы, using the Intel card, perform way better at about 2000FPS. I know that the NVIDIA card should pull about 4000FPS on this тесты.

Is there something гm missing here? Please help :)
