Well I got Crossfire to work by disabling AA ingame and forcing it in CCC and using Supersampling. Only scaled up 20fps, however. Problem is now the FOV Changer does NOT work in CF (for me).
SP Game runs perfectly well (for me) with 13.12 even at 2560 x 1440 with one XFX 7970 TDBC and even a bit better by bumping up the gpu clock 30Hz and memory clock by 45Hz...everything on Ultra/High...60-70+fps. Increased cpu from 3700MHz to 3900 and increased cpu voltage .0125v...
Game is pretty memory hogging, so you may want to disable as many backround apps and processes as possible when playing.
Hoping next drivers address this issue.
Been a tester and player for years and Ghosts is the best FPS I have ever played! No sympathy or empathy for those that got an unlikely refund.
UPDATE: Added "iw6sp64_ship.exe" file (<<...steamapps...Common...COD Ghosts) to Application Settings and turned on Morphological Filtering on as AA and got better framerates, but still does NOT look as good as a single card (still a very minor amount of flickering floor /ground textures).
