Our Settings for Far Cry 3
Even viewed under the FRAPS light, Far Cry 3 has some issues with CrossFire but when we take out runt frames and any drops, the observed FPS drops quite a bit lower.
Both the green and black lines that represent the single card results indicate a good gaming performance with thinner, tighter bands of frame times. Both multi-GPU solutions vary from that though CrossFire without question has the harder time keeping an even distribution of frames.
Both SLI and CrossFire prove to scale the "average" FPS in Far Cry 3 at 1920×1080 but the orange line that represents frame rates for the HD 7950s in CrossFire quickly fade down and away from the more consistent line of the GTX 660 Ti cards in SLI.
Potential stutter as determined by our frame variance results show the CrossFire solution to be much more susceptible while the GTX 660 Tis in SLI are stay within the same range as the single HD 7950.
The frame rates for the HD 7950s in CrossFire differ greatly once again from the FRAPS reported metrics to our new Frame Rating results.
The mass of orange, and the gaps in the timeline completely, tell us that something bad is going on again; this time we have drops in addition to runt frames on the HD 7950s in CrossFire:
SLI actually scales pretty well in Far Cry 3 at 2560×1440 with the GTX 660 Ti moving up from 22 FPS to about 42 FPS on average while also minimizing the stutter and hitching in the game.
CrossFire just can't keep up with frame time variances as high as 50+ ms!
This resolution is incredibly hard on all of these cards and this is one case where the problems with CrossFire were bad enough that our scripts weren't able to properly guage performance with the number of dropped frames we saw.
Our plot of frame times needs to be scaled back some to show the whole story, but honestly when we are regularly exceeding 80 ms frame times, there isn't much pretty to look at. GTX 660 Ti cards in SLI though are clearly not powerful enough to keep up with Far Cry 3 at Ultra settings at 5760×1080.
A 3GB frame buffer on the HD 7950 gives us a better single card result in terms of frame rate when compared to the single GTX 660 Ti and the experience found on the SLI configuration quickly deteriorates.
All cards show some noticeable frame time variance including the single card options though the GTX 660 Tis in SLI are much worse.
