Mid to late game lag

[Adijedi]

So I was one of the people who had straight off the boat lag where the game stuttered. Thankfully that problem was fixed by 1.0.1

However now I'm having a problem with the game being very slow in the midgame (year 2358 ingame) 1000 star galaxy, elliptical etc. Is poor performance in the mid to late game just something I have to deal with or is there a solution in the works for that? Is it a matter of optimization, or do I just have to accept that my fleets are going to move in pulses slowly to their targets?

Any ideas on how to reduce this lag would be helpful, or preferably a patch.

I can post any info about my system or degub info or saves if requested. I'll say right off the bat that I am running windows 10 64 bit on a custom made desktop with a GTX 960 and a 12 core (4 cpu and 8gpu) processor plus 16GB of RAM, so I'm 99% sure that my system isnt the problem.
