How to fix the performance issue when running nvidia surround?

I am having a huge performance issue (unusable) when I’ve activate nvidia surround to run my 3, 1080p monitors to run at a resolution of 5760x1080. However, when I deactivate it the unreal engine runs phenomenal.
Computer hardware:
CPU- i7 6700k
GPU- GTX 980ti + GTX 750ti (issue isn’t solve when I disable the 750ti)
RAM- 32GB 2666mhz DDR4
Hard drive- 3TB
SSD- 256GB (where the engine is installed)
I hope this issue will be fixed soon
