AMD Chief Gaming Scientist Richard Huddy speaking at the PDXLAN event apparently misspoke when he said that Windows 7 will not support DirectX 12. There had been reports based on a video of Richard Huddy of AMD making speculative comments around DirectX 12 support on versions of Windows. Basicially he said that Windows 7 would not be able to run DirectX 12.
However AMD said in a statement. "Richard Huddy does not speak for Microsoft, and he was unfortunately speculating from Microsoft’s publication of key dates and milestones for Windows 7 lifecycle and mainstream support policy.
“Richard has no special insight into Microsoft’s Windows or DirectX roadmaps. Microsoft is a key, strategic partner for AMD and we’re continuously collaborating with them on DirectX 12."
However PC gamers are worried about the possibility that DirectX 12 won't work on Windows 7. The fear is that if they want to use the new DirectX 12 games they will have to upgrade to Windows 8 or the upcoming Windows 10. Microsoft previously said that DirectX 12 will work across PC, tablets, phones, and Xbox One. It didn't say if it will support Windows 7, but that it's aware of the demand for Windows 7
