I have a single HD6990 (dual GPU) and only 1 is working with 1.4, still getting good frames and no complaining, but after trying the 1.5 PTS to see the cartel market I found both GPU's were working when observing with MSI Afterburner overlay. I would suspect 1.5 will be out the first week of november, so not a long wait from now to get crossfire working, that or ccc.exe is not recognizing the main swtor.exe and only noticing the PTS swtor.exe. All I can say is on a HD6990 I am getting both GPU's working in PTS
