My platform is a dell xps16 (old) with Windows 8 x64.
I have installed the latest (legacy) driver for the ATi Mobility Radeon HD 3670 from the ATi website. But my device management in Windows tells me that I have this 8.970.100.3000 version from AMD.
gfx.blacklist.direct2d set to 3. (not by me! )
When I remove all ATI stuff, it uses ATI Mobility Radeon HD 3670 (Microsoft Corporation - WDDM v1.1) which is also fine, because it feels faster with the metro interface. But I also have the disabled direct2d and webgl in firefox.
when I open setup.exe from fresh downloaded
AMD_Catalyst_12.6_Legacy_Win8 I get this screen which will install version 8.970.100.3000 and the utility from the ati website also redirects me to the same download from the ati website as the manual selection does. sorry for the dutch screenshot.
Ps. Already rebooted the pc after the driver installation. And webgl is also not working with chrome 24.
