Civilization: Beyond Earth CrossFire with Mantle SFR: Not Actually Broken!
 

Yesterday after an all-day session of benchmarking on Wednesday, we published our initial performance results for Civilization: Beyond Earth. As can often be the case with limited testing, we ran into a problem and were unable to find a solution at the time. In short, while there was a lot of talk about how developers Firaxis had spent some effort to improve latency using a custom Split-Frame Rendering (SFR) approach with Mantle on CrossFire configurations, we were unable to produce anything that corroborated that story. Emails were sent, but it took half a day before we finally had the answer: enabling SFR actually requires manual editing of the configuration file. Oops.
