Patch 1.01.14588 Xfire not working
 

Just a heads up but after checking the Il-2 Sturmovik: Cliffs Of Dover Retail Patch v 1.01.14550 version that I had backed up it appears that the GAME VERSION 1.01.14588 patch has switched off Ati Xfire support as it worked before the hotfix was released.
I tried Xfire in two other games and I get the Xfire icon in the top corner of the screen and both cards have temperature increases whereas in Clod I get no Icon and only the Primary Card warms up.

It works for me. Not very well at all, to be sure, but technically it's working for me with that game version.

It seemed to work much better in the previous version, and with the new, harsh lighting and bizarre prop effects, and other "anti" progress, I personally have decided to give this thing a good long rest.
