Far Cry 3
This is our first time testing Far Cry 3. I picked one of the first assassination missions, shortly after the dramatic intro sequence and the oddly sudden transition from on-rails action shooter to open-world RPG with guns.
The game was run at 1440x900 with MSAA disabled and the "Medium" graphics quality preset selected.
Far Cry 3 is a very graphically intensive game, and at the image quality settings we've chosen, both cards struggle intermittently with delivering smooth gameplay. The Y axis on the plot has been stretched to show the 7690M's lone spike to around 180 ms a third of the way into the run. (Yes, it happens every time.) However, you can see the 8790M suffers from relatively frequent spikes over 40 ms, especially toward the beginning of the run.
At the start of the run, those spikes manifest as a kind of jumpiness or jerkiness in the animation. Oddly enough, the effect is worse than in Borderlands 2, even though the spikes tend to be shorter.
The 8790M's 99th-percentile frame time is lower here than in Borderlands 2, at least. 39.8 ms works out to around 25 FPS.
Our latency plot shows the 8790M's frame latencies are fine through about 97% of the run. Only the last 3% of frames seem to pose a problem. Because the 8790M is so much faster, though, even its worst frame times aren't too much higher than the 7690M's are generally.
The 8790M spends very little time working on frames that take more than 50 ms or 33.3 ms to render. That reflects what we see in the frame-time plot, where the 8790M's latency spikes are generally short and clearly become infrequent after the first 500 frames or so. There are only two exceptions where unusually high spikes disrupt gameplay.
The 7690M only sees one exceptional spike, but because the GPU is relatively slow, it nevertheless spends over two thirds of the run working on frames with latencies above 33.3 ms. Far Cry 3 feels sluggish and choppy on that GPU.
