GTX 1080 Ti SLI performance: per game

There are great differences between how much performance boost SLI provides per game. Some games do not support SLI at all, while others show a marked improvement. Here you can see the performance boost each game showed in Ultra HD Ultra.

  GTX 1080 Ti GTX 1080 Ti SLI Gain
GTA V - 3840x2160 - Very High 38 59,1 55,5%
Project Cars - 3840x2160 - Ultra - MSAA 124,7 193,9 55,5%
F1 2015 - 3840x2160 - Ultra 74,9 70 -6,5%
Rainbow Six Siege - 3840x2160 - Ultra  41,9 40,2 -4,1%
Far Cry Primal - 3840x2160 - Ultra 56 70 25,0%
The Division - 3840x2160 - Ultra 53,9 78,6 45,8%
Rise of the Tomb Raider (DX12) - 3840x2160 - Ultra  58,2 111,8 92,1%
Battlefield 1 (DX12) - 3840x2160 - Ultra 65,2 61,8 -5,2%
Watch Dogs 2 - 3840x2160 - Ultra  44,7 73 63,3%
Doom (Vulkan) - 3840x2160 - Ultra 111,1 100,7 -9,4%
Civilization VI (DX12) - 3840x2160 - Ultra 79,2 77,4 -2,3%
Average     28,2%

Some of these games, like Battlefield 1, support SLI in DirectX 11, but can't use DirectX 11's new Explicit Multi-GPU feature. The only game that does support Explicit Multi-GPU is Rise of the Tomb Raider, and it shows an enormous gain of 92%. While we have earlier seen similar percentages with slower cards, the gain is usually smaller with faster cards. This is a good portend, at least if developers take the time to program for Explicit Multi-GPU. The other games that support SLI show a boost of around 50%, except for Far Cry Primal, which shows an improvement of 25%.
