Mantle API - Compatible and Selectable?

For me Mantle adds micro stuttering and nothing else

Thanks Admiral! I'm not sure if windows tried to update me, cause I wasn't there during all the reboots. Retrying.

Okay, it isn't windows update. I'm guessing there's something off about the HD 7660 specifically. I can run the game fine under directx11; I have 20-35fps with the meshes, textures, terrain and water on medium; still, mine is just the sort of machine which would benefit greatly from mantle. <heavy sigh>

The Radoen HD 7660D card is based off the Radeon HD 6900 desktop series, which is not supported by Mantle.

AMD's card numbering schemes, especially on mobile chipsets, are hilariously misleading and bad.
