I recently installed a new Gigabyte R7 265 in my daughter's computer and cannot make any driver newer than 13.251 work, and therefore cannot take advantage of Mantle. I have followed AMD's instructions as to removal of old drivers and installation of new. I have followed Tom's guide to removal with all of it's in depth registry edits and whatnot. Nothing has worked. Every time I try a newer driver (after following one removal guide or another) Catalyst Control Center will not run, and hardware monitor can detect no discrete graphics card.
What am I doing wrong? Is there Mantle in 13.251, and I just need to do something in BF4 to enable it? The DirectX/Mantle selection that I've seen in the video options in so many BF4 mantle tutorial videos simply isn't there!
The computer is an i7-920 and 6 gigs of ram on a Dell proprietary motherboard, operated by Windows Vista Pro 64 bit.
Thank you in advance for your help.
