Every graphics card has certain problems with the bottom speed in BioShock Infinite, so it must be due to the game engine or test scene. It doesn’t seem to be a hardware problem.
As for average frame rate, the SLI technology is 75 to 93% efficient, making the GeForce GTX 760 tandem much faster than the GeForce GTX 780.

Nvidia’s SLI technology doesn’t work smoothly in this game yet, but the two GeForce GTX 760s are anyway ahead of the single GeForce GTX 780 both with Advanced PhysX…

This game had also been updated before our tests. The 2-way GeForce GTX 760 SLI configuration beats the single GeForce GTX 780 in three out of the four test modes.
We had to choose the AFR2 mode in the driver’s control panel to enable SLI in this game. Otherwise, there was no performance boost at all.
