Do tell me that graphics and video software is not games?
You got a notebook with X4500MHD you can't make it be something else that its not.
If your sure the software you want to run on your notebook can ask the software maker on how to bypass the requirements.
The software that I'm trying to run is a game, "NBA 2k9", and it ask NVIDIA GeForce 6600 as requirement in video.
With GMA X4500MHD installed in my notebook, this game doesn't run ok, because its graphics don't showed correctly.
The X4500MHD is not intended to run games no matter what you do.
