It is unacceptable that do not support Windows 8 in the series 4000, 3000 and 2000.
NVIDIA GPU´s supports built until 2004.
My next GPU will be a NVIDIA. And if you ask me that what gpu recommended saying: NVIDIA
Sorry for my english
While I understand your desire for support for the 4000 series, Windows 8 is still months away from being officially released so I'm a little more understanding and patient with AMD until then.
I wasn't aware of that, so I searched and found this from http://support.amd.com/us/kbarticles/Pages/catalyst126legacyproducts.aspx:
Note: The In-the-box AMD graphics driver that is included with Windows® 8 will include support for the AMD Radeon HD 4000, 3000, and 2000 series, and it will support the WDDM 1.1 driver level features. Please also note there will be no support for AMD PowerXpress™ feature on the mobility variants. The AMD Catalyst driver for Windows 8 will only include support for WDDM 1.2 support products (AMD Radeon HD 5000 and later), and will not support the AMD Radeon HD 4000, HD 3000, and HD 2000 series.
So it seems to me that is/will be support for those older devices in Windows 8, AMD just provides it indirectly through Microsoft rather than as a download on AMD's website. That kind of driver support is more familiar to Mac OS users.
Does the driver distributed via Microsoft Windows 8 include the full acceleration and OpenGL support that was available in the Catalyst drivers? Can users expect the same performance with the Windows 8 driver as they got from the drivers distributed by AMD directly?
