No version of Max supports DX11. Though it looks like they will support it in the future. http://area.autodesk.com/forum/autodesk-3ds-max/autodesk-3ds-max--3ds-max-design-2011/when-autodesk-will-catch-up-with-the-world--will-they-ever-/
Hi, can someone tell me how to change the rendering mode from DX9 to DX11 in 3DS max 2012, it used to be under the choose driver setting in 2011 however all I have there now is the option to revert from DX mode
