First sorry for my english, long time I didn't practice...
I would like to use CrossFire with Watch dogs 2, Battlefield Hardline, and some other games.
With my GPU config (2x R9 270X OC) I tried to enable CrossFire to improve graphic performance.
The lastest AMD driver update (17.1.2) doesn't allow Crossfire in any game. It launches correctly, then crashes after a couple of minutes of playing. It is the same thing with only one active graphic card.
I tried everything I found on the net. DirectX update, Vcredist update... several crossfire profiles... doesn't work.
The best way to play is to downgrade AMD driver to version 16.11.5. With this one, I can play Watch Dogs 2 for approximately 1h then, it becomes slow and crashed out.
With this previous driver version and with Crossfire disabled, I can play for hours without any problem, but with poor quality graphics... With this driver version, I can't run Farming simulator 2017 however it works with 17.1.2. I didn't tried compatibility with other games...
So if I want to play to different games I have to install different driver version for each game ?
It seems strange that 17.1.2 cannot do the same things and better as 16.11.5...
Maybe I'm doing something wrong ?
Maybe that trust in crossfire is the biggest mistake I did ? Will AMD repay my second useless graphic card or change both of them for a single RX 480 8Go ?
Many thanks for your help !
