Can you show me a screenshot of your desktop
Sure. Its a bit messy but here it is.(http://i.imgur.com/ffRv7kX.png)
I know that this is not very common res, and this setup was made mainly for Elite: Dangerous, but after a while, i tried alot of games on it and yea, i must say that wider is better.
Edit: Ok i think that i solved the problem. The 5760x1080 is too much for this game thought. So i tried some other resolutions and 3072x768 is probably maximum for me now. Its not perfect, but still allows me to use my all 3 displays. Higher res has serious scrolling problem especially on smaller maps.
