Doesn't even work in Xfire at all now, turned FreeSync off, tried to start a rally, but everytime the stage loads now, instead of starting it, it just sits on a black screen for about 2 seconds, then i get a BSOD, shutdown to prevent damage, physical dump job, then it restarts.
Runs fine on a single card, FreeSync on or off as well.
When i was on the 15.9.1 BETAs, it was fine in Xfire, when it worked, as i got the random back to desktop when the stages loaded with FreeSync, which was mentioned in the release notes of the drivers as being a known problem, crashing with FreeSync and Xfire in Dirt Rally.
Nothing wrong with my cards, as just ran through FS in Xfire to check em, and it was fine.
I'll be going back to a single card when the new ones come out (i run in single card mode now anyway tbh), as Xfires garbage, its just got too many problems.
