I don't seem to be having any FPS losses w/ an i5-4670K. I don't think I saw this anywhere in the thread but I'm having an issue where things like decouplers will be unmuffled for a split second when staging, which sounds jarring compared to everything else at around 35-45km. Has this happened with anyone else? Using stock decouplers at the moment.
Oh yeah, also noticed this extending landing legs on the mun.
