14.4 RC crossfire 290s xfire won't work in games but does in gpu-z test

[Unoid]

I swapped out my 680's for my 290's that were mining for the past 4 months.

I uninstalled nvidia and rebooted to safe mode and DDU removed all nvidia (except physx). I Rebooted and installed 14.4 RC drivers with both cards plugged in. Crossfire says enabled in both the driver manager and also in GPU-Z

I run GPU-Z PCI-E bus test and it shows PCI-E 2.0 x8 for each card. xfire works with 100% usage over both.

I'm running a 2600k Sandy on an ASRock extreme 4 gen 3 (supports pci-e 3.0, however sandybridge's only do pci-e 2.0

How come in every game I try (thief, bf4, natural selection 2, etc. ) only one card is being used? GPU2 sits at low clocks and 0% usage.

am I missing something? thanks for the help.

edit: I already disabled ULPS. Also Unigine Valley benchmark, both GPus do work in crossfire.

I've had that issue before and did all the things you've done and the only fix I found to work 100% was a new install of my OS.

EDIT 2: I'm a dumbass. All my games were setup for windowed fullscreen. Games require Fullscreen for crossfire, unlike nvidia's. DELETE Thread please.

Delete thread if possible.
