I finally discovered why I was experiencing so many issue under Windows 7 x64 after upgrading from Windows Vista x64. The OpenGL version is 1.1.0 therefore I am currently using the Microsoft Generic driver.
Is it possible that a Windows 7 driver for my ATI FireGL 7200 is not available?
I tried downloading the following two drivers from AMD.com:
but cannot be installed (the install program disappears without reason).
Any help is greatly appreciated thanks.
