The Witcher 3 at 5760x1080 was giving my GTX 1080 Ti a pretty good workout (about 50-60 FPS).

So many more pixels than 2560x1440. At 7680x1440, I'll need two of those GTX 1080 Ti's in SLI to get anywhere close to 60 FPS at that resolution in Surround.

I just wish developers start implementing Simultaneous Multi-Projection into their games, be it through a patch, or implemented during the development process. SMT, as demonstrated by NVIDIA, corrects the distortion of the left and right displays through the use of multiple viewports, which makes the image in triple-display surround setups look correct and not distorted.

But Surround provides a totally unreal level of immersion still. It's insane!
