not sure why but for the last week or so i get odd fps issues with dirt2 and farcry2 , i get less fps in crossfire than i do with a single card . sometimes they run fine but most of the time they run reduced fps , even had afterburner running to see what scaling i get . in avp gpu 1 is 99% and gpu2 is @ 92% , it is nearly the same in metro2033 (99% + 90% ) .

but in farcry2 they both run 54% at max settings (everything maxxed with 8x aa) , sometimes they will run @84%+ when it is running well and no matter what driver i use it is still 9 times out of 10 running worse than running a single card . dirt2 does the same when benchmarking in crossfire mode , in crossfire i get an average of 72fps but with single card i get 83fps average . do these games not support crossfire well ? , or is it a driver issue ?
using 10.12 with cat app profiles installed

I had this issue roll back your driver to the last version, also use this: http://www.guru3d.com/category/driversweeper/

tried it and used driver cleaner , i still get the same .

i have tried every driver since 10.5

I dont have these issues on single gpu pfffft, do you really need CF, i doubt it.

starting to wish i had not purchased the second 5870 lol , should have gone for the gtx570 or waited for the 6970
