If you can code on Unity and would be able to optimise the work of Manyakis, then sure. He's working on this project mostly alone afaik, probably unable to afford actual programmers to do the coding (either due to lack of sustainable funds or due to refusal to accept any form of free labor. Or both). If/when he figures out how to apply optimisations, I'm sure he'll do it. But until then, I personally would only suggest setting graphics a bit down? I personally run it on 7th gen Intel Core i5 processor and GTX 1060, and everything is fine at average graphics and 60 fps lock, in windowed mode. Aside from maybe a little bit of lag whenever things load in. Although I do agree, the load on GPU is crazy whenever the game is running.
