Projection Mapping Tool Problem

Hi all, I am recently doing a project that need to output six 1080p outputs to six projectors and do the 2d projection mapping as well.

I am using Kantan Mapper. But I found this tool is so heavy, causing 20 fps drop.
So I wanna ask if there is any other tool better than Kantan mapper or if there is anyway I can improve the performance with Kantan Mapper?

Thanks in advance!
