Lag with Interstellar

[Expwnential]

Hello Fellow KSP Users,

I have a pretty good rig for ksp (i5-4670k, Radeon 7990 6-gb, 16 gb corsair, etc etc.) and I recently installed Interstellar. I am able to run 500 part stations with no fps drop but I recently built this thing in orbit:

It has 180 parts and lags like crazy (<10 fps, yellow timer on the top left) and im 99% sure it has something to do with the interstellar parts. Anyone know what it is and how I can go about fixing it?

Thanks

I also have this problem. I have built something larger than this with higher computer specs than yours, and the vehicle still lags me down to really low FPS. Only when I'm controlling it specifically though. If I'm in kerbal EVA right next to the thing it runs at a smooth 60 FPS. I can't think of anything that would cause this other than a mod bug. Graphics settings have no effect and changing the Delta T only masks the lag problem.
