The current driver available at Asus support website is the version 268.74. It runs really good, however I need atleast version 270.81 of the driver to be able to run nVidia Parallel Nsight 2.0.

So I would like to know how often does Asus update the GPU drivers? Or is there another way to update the drivers? Those at nVidia website can't be installed because this laptop uses Intel switchable graphics.
I need it ASAP or I will be forced to return my Asus and get a new laptop with ATI GPU.

Thanks in advance.
