Crysis 3
Yep. This is the new Crysis game. There's not much else to say, except that this title has truly spectacular graphics. To test it, I ran from weapon cache to weapon cache at the beginning of the Welcome to the Jungle level for 60 seconds per run.

I tested at 1080p using the medium detail preset with high textures and medium SMAA antialiasing.

Both versions of the GTX 650 Ti Boost have problems with uneven frame delivery—and frequent latency spikes—in Crysis 3. Those problems don't seem to hurt the cards' FPS rankings:

However, our 99th-percentile frame time metric shows the GTX 650 Ti Boost cards at the back of the pack. Shockingly, the reference model even falls below the Radeon HD 7770. (The results are all awfully close, though.)

Our percentile curves nicely illustrate the problem. While our two GTX 650 Ti Boost variants have lower 50th-percentile frame times than the competition, those times start to rise around the 80th percentile. The Radeons—and even the other GeForces—don't really begin to ramp up dramatically until above the 95th percentile, which suggests that they maintain both lower and more consistent frame times throughout a longer stretch of the run.

The early rise of their latency curves might look ugly, but the GTX 650 Ti Boost cards don't look so bad in our "time spent beyond" metric. They fare poorly in the beyond-33.3-ms rankings, but not dramatically so. (493 ms is less than 1% of the 60-second run time.) What gives?

Well, look back up at the frame-by-frame graphs. Most of the see-saw pattern is sandwiched between 5 ms and 30 ms or so, with very few spikes above that threshold. The problem in this case isn't really a propensity for long spikes that make the gameplay stutter (which our "time spent beyond" graphs isolate), but a very rapid oscillation between long and short frame times. If small, such an oscillation isn't a problem. In this case, however, the oscillation is large enough to disrupt gameplay. It feels a little like wading through water: animation seems to speed up and slow down randomly, and input ranges from very responsive to noticeably laggy.

Considering the GTX 650 Ti 2GB doesn't seem affected despite using the same GPU with fewer units at a lower frequency, I'm tentatively going to chalk up this problem to a driver optimization issue. I'm not sure why the GTX 650 Ti Boost would behave so differently otherwise.
