Crossfire since Hotfix
Since the hotfix I was getting more stutters with Crossfire enabled than before. I spent a lot of time tweaking the system yesterday - wanted to go on line on ATAG but decided to try to solve the issues before attempting playing on line. In the end I spent hours messing about and never got to fly! Damn!
I found that I needed to increase the GPU overdrive to max settings (Catalyst Auto Tune max limits) to improve the performance. Interesting that, before I adjusted the settings, the cards were both kicking in but only using about 30% of capacity. Whereas, before the hotfix they were maxing at about 90%.
Now, they each run at about 60% with no penalty on temperature - they get to 68 degrees and sometimes touch 70. Warm but not too hot.
I have CLoD settings pretty much maxed out so performance demand can be quite extreme. Not absolutely perfect, I still get some annoying microstutters and some shimmering on the horizon but not drastic.
In summary, I guess the hotfix has enabled Crossfire to work properly but I have no yardstick to compare anything and have no experience of SLI on Nvidia cards.
Just thought I would throw that info into the mix.
