Frame Rating: AMD Improves CrossFire with Prototype Driver
DiRT 3 (DirectX 11)
A continuation of the Colin McRae series, but without his name, DiRT 3 is one of the top racing games in the world and offers stunning imagery along with support for features of DirectX 11.
Our settings for DiRT 3
More positive results from the new prototype driver compared to the 13.5 beta release with no runt frames showing up and only modest changes in the perceived frame rates.
The orange masses you see in the middle are indicative of the alternating high and low frame times with runts, but you can see who the new prototype driver has improved things with no instances of runt occurrence.
The 50th percentile represents the average frame rate of over our runs and you can see that both the 13.5 beta and the prototype driver on the HD 7990 start out in the 130 FPS range. The orange line quickly drops off though after the 70th percentile but with the new prototype driver the frame rates stay much more consistent.
The frame variance data still tells us that the GTX 690 and GTX Titan still have the least frame to frame variance against the HD 7990 even with the new driver. The improvement over the 13.5 beta driver is noticeable though.
