bumblebee-nvidia working but graphic card seems 256MB while its 1GB

I run unigine-heaven test that i downloaded from AUR.

Here is the result

Unigine Heaven Benchmark 4.0

I tried it with "optirun" - "optirun -c yuv" - "primusrun". Pretty much the same.

And results from windows.

I dont expect great things since 3d support in linux still new. But the problem is i didnt get the part "Unknown GPU".

When i try

$ lspci | grep -E "VGA|3D"

i get

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev ff)

What does it mean. Does bumblebee cant detect my graphics card which is nVIDIA GT540M (1GB). Is there some step i missed.

Thanks in advance.
