Mantle Bf4 Cgminer

[dwolfx]

Setup
R9 280x miner
R9 270 Miner
R9 270 (Gaming).

I was running like this for a while, no problem (no fps loss while gaming and mining at same time), then I updated to mantle, and again everything was running great mining on 280x and one of the 270x's at same time no problem.
Then today, I can only mine on the 280x and play bf4 at same time.
For some reason launching cgminer on the un-used 270 causes a shit-storm with the driver(even though it was running fine yesterday).

Anyone encounter this problem, I know I can just solve it by rolling back a driver, but Mantle is pretty sweet for Bf4, the fps gains on my end were quite noticeable ;p i leave all three cards mining scrypt most of the time, but sometimes I wana just sit down and play 2 hours of Bf4 for the hell of it.

Probably gona re-install 14.1 and try again from scratch and hope it fixes, anyone else encounter this or?

Update: After trouble shooting, I seemed to have found the solution.

If you go into, My Documents and you delete the Mantle cache files inside of Cache folder for battlefield and delete the settings files (back them up if you want) it seems to reset the game.

It's seems it was a strange glitch with mantle.

For some reason Battlefield was rendering on a different card than the monitor was plugged into. so card 1 was intended battlefield card.... but battlefield was rendering on card 2 and passing the vga signal through card one, (no idea why).... seems mantle got a little mixed up with the path it was taking for rendering.

Back to hashing and fragging at the same time with mantle , woot.
