Ah I was getting the same problem. I narrowed the FPS drops down to the dishes also, but I can get away with 4-6 depending on size of ship. My specs are: AMD Phenom II X4 965 not OC'ed (although I temporarily bumped it up to 4.06 to see if it would help FPS drops. Not much effect.) 8 GB RAM EVGA Nvidia 570 GTX factory OC'ed Other bugs I've noticed in .17 is that Show path on map doesn't actually show any lines although it does give the relay path on top of the window. Celestial objects don't block radio signals properly unless I switch vessels and switch back, and only sometimes works after that. Throttle controls are moving much slower as well, about 50%, even when sitting on the launch pad. Also killing the throttle (ctrl + x) isn't cutting it properly. Only cuts throttle to about 50%. Removing the remote module or switching to local control removes the throttle issue. This last one, I don't know if it's mechjeb or this causing it, but when using the remote SAS stacked on top of the mechjeb 1m edition the auto ascend will not steer the ship, but staging and throttle work as normal. Putting the mechjeb module anywhere else on the ship, even right below the remote SAS seems to work though. Also, I want to say thank you so much for this awesome mod! It's one of my favorites!
