Just Cause 2

Unfortunately, the benchmark integrated into Just Cause 2 does not report the bottom frame rate but the average speed data indicate that the GeForce GTX 660 Ti cards provide high scalability in the 2-way tandem and above-average scalability in the 3-way configuration. We should also note that the dual-processor GeForce GTX 690 isn’t much slower than the GTX 660 Ti trio.

Aliens vs. Predator (2010)

SLI technology works even better in Aliens vs. Predator (2010): the tandem offers twice the average frame rate of the single card whereas the 3-way SLI adds 42 to 47% more.

Lost Planet 2

Being a CPU-dependent application, Lost Planet 2 can only show us the SLI effect in the heaviest mode, i.e. at the resolution of 2560x1600 pixels. But even with enabled antialiasing the two GeForce GTX 660 Ti cards are only 66% ahead of the single card and the 3-way SLI configuration is a mere 16% faster than the tandem. This isn’t high scalability at all.

Sid Meier’s Civilization V

Although CPU-dependent as well, Civilization V allows the multi-GPU configurations built out of GeForce GTX 660 Ti to show their best in every test mode. At 1920x1080 the 2-way SLI is 89 to 95% faster than the single card while the 3-way SLI is 45 to 46% ahead of the tandem. That’s very good. As for the resolution of 2560x1440 pixels, the 2-way SLI configuration boosts performance by 92-93% and the 3-way SLI adds an extra 46-48%. Running ahead, we can tell you that SLI technology shows its near-maximum scalability in this test. Meanwhile, the GeForce GTX 690 with its two top-end GK104 processors is almost as fast as the 3-way GeForce GTX 660 Ti setup.
