been playing Overwatch and Destiny , had this problem for a while and cant seem to figure out why it wont use the full potential of the cards, they scale maybe 10% in SLI

in both games , seeing only about 30-50% usage of each card MAX , with max settings , which means in certain parts of the game im dropping to 60 fps , im tryna keep a solid 144 fps since have a 144 hz monitor and feels so much better , disabling SLI uses 80-90 % of one card and getting practically the same FPS.
 
I can't offer specific help. but I can say that SLI support isn't universal and it isn't going to guarantee a certain amount of gain. One game may not use it, one game may try to use it but not work right, another game may benefit a little, another game may gain a large benefit.

So your first task would be to research how Overwatch and Destiny do with SLI. You can be sure that if there were consistent benefits to SLI then more people would be using it. Instead, most people just use one, fast card.
 


Both games support sli, and for example looking up benchmarks on destiny 2 people are avg over 120+ with sli 1080's when as I avg maybe 70-100, pretty positive its due to low gpu usage in the games that in seeing / others have seen but their issues seem to be more with gsync causing low gpu usage ( I don't have a gsync monitor)
Side note : running benchmarks like fire strike both cards get up to 85% so it's not a Bad sli bridge ( using a HB bridge)
