Issue Details
I have enabled crossfire before installing CCC 13.1. Then the automatic updater told me that there is a ew version available and I installed it. Now with CCC 13.1 I can't find anything about crossfire anymore. All I know is, that it is enabled, since some games warn me about it.

Question: Where do I find the crossfire settings in the new CCC? I got huge performance drops in some games since the Update and it might be connected to Crossfire.

Phew, good question. 750W afaik. Is this very important ?

Thanks for the help.

Apparently the CCC 13.1 turns of the crossfire tab. So you are not able to change the settings you entered with the older version.

Reverted back to CCC 12.6 until this is fixed.

For those with similar problems: You can find the previous Version of CCC in the "Previous Drivers and Software" section when looking for your latest driver.
