Frame Rating: Catalyst 13.8 Brings Frame Pacing to AMD Radeon
Battlefield 3 (DirectX 11)
Battlefield 3™ leaps ahead of its time with the power of Frostbite 2, DICE's new cutting-edge game engine. This state-of-the-art technology is the foundation on which Battlefield 3 is built, delivering enhanced visual quality, a grand sense of scale, massive destruction, dynamic audio and character animation utilizing ANT technology as seen in the latest EA SPORTS™ games.
Frostbite 2 now enables deferred shading, dynamic global illumination and new streaming architecture. Sounds like tech talk? Play the game and experience the difference!

Here is our testing run through the game, for your reference.
Immediately we see some good results! The most important comparison here is between the orange line (HD 7990 with the 13.4 driver) and the black line (HD 7990 with the new 13.8 driver and frame pacing enabled). Compare the lines in the first two graphs - FRAPS FPS and observed FPS - notice how the orange line dips dramatically from FRAPS to observed frame rates? The black line does NOT do that indicating we are not seeing runt frames!
The frame times graph clearly shows that difference at work as the black line of the HD 7990 with the latest beta driver and frame pacing enabled is MUCH tighter than the orange line. The result is frame time variance that never gets out of control and stays within 2-3 ms. Looking at the FPS by Percentile graph you can also see that because of these changes the observed frame rates are much higher and actually push the Radeon HD 7990 well ahead of the GTX Titan and the GTX 690.
The same story is repeated here at 2560x1440 - the new 13.8 driver with frame pacing produces a MUCH better result! The frame times aren't quite as consistent and smooth as the GTX 690 still but the improvement over the previous driver iterations is clearly night and day.
