Hello, everyone!

Now, I am calculating transmission pathway by using ATK-11.2.3. However, my color bar always shows red. That's why? who can help me ?

This is due to a bug in your graphics driver, most likely. I can normally be solved by upgrading to the latest driver version provided by the vendor (not the one that comes with your Windows/Linux distribution).

I use windows 7 (64 bits) operater system, and my mainboard is （GIGABYTE）GA-B75M-D3H(Intel B75/LGA 1155).

Thus, my graphics card is integrational.

How can I get the latest graphics drivers?

No idea, try Windows update? In general we recommend that you have a dedicated graphics board (NVIDIA or ATI) for using VNL, it will give a lot better performance as well.

Thank you very much!

I will buy a dedicated graphics board later. Is there any requirement on the dedicated graphics board ? 1G or 2G?

The more the better :) But there is no huge difference unless you plan to work with really big models. Fortunately today the price difference is also probably quite small.
