I would have to change render pipelines, so certain graphics features would no longer be possible. This is something I will consider, but if it does happen it would require a lot of work.
With the V10 update, I have added a 'Minimum' graphics option. I have not tested it on low spec PCs, but it should run a lot more smoothly than before. Keep in mind this game is very CPU limited, meaning even with the lowest graphics, you will still be bound by how fast your CPU is.
