Recent Slow-downs?

[SgìobairOg]

Wanted to see if anyone had noted any recent slowdowns on their systems? I'm getting some slowdown on larger part-count rockets and ships, which is to be expected to some degree, but I'm getting crippling slow-downs on ships with less than 150 parts. More puzzling is the fact that it seems to be recent and worse in .22 than .21.

Now, before people go ripping on about this being "a development out of Squads heart, not deep pockets," or, "still a beta," I understand that, fully. I am simply trying to diagnose whether there is a problem with my setup, my computer or the game code itself. If it's with the game, I'm trying to see if it is something Squad knows about or if it is something to be brought up.

I'm playing on an iMac 2.9 GHz Intel Core i5; 16 GB DDR3 at 1600MHZ; NVIDIA GeForce GT 650M 512 MB; running OS X 10.8.5. I know that video card is nothing special but my understanding is that the CPU is the choke point due to the physics calcs. The CPU seems like it wouldn't be that bad. On the CPU front, not entirely sure what to make of my activity log details. I'm seeing up to 130% CPU usage for KSP's process but also 30% user usage for the CPU in general. Maybe someone more familiar with Macs and Multi-core processors can make more sense of that than I can.

There anything going on here other than "need more CPU"? I seem to exceed all recommended specs but I know those were also estimated recommendations and with .22 may not be entirely accurate.

I've also observed a lower threshold before lag sets in with .22. Not sure if it's happened to everybody, though.

I started using turbojets to launch things into orbit, and the smoke from those things seems to create significantly more lag than liquid booster smoke

it also doesn't help that I am using some B9 radial turbofans that have an animated spinning blade. I wonder if I could shut those off?

(I almost feel like I should rant on how you shouldn't be using a mac)

Have you tried running it straight after a reboot? As in (close as can be anyway) nothing else is running

I used to be able to replace the starfield using Universe Replacer with next to no lag, but now I experience slowdowns whenever I try it. Not sure if it's a problem with the most recent version of that mod, or 0.22, or I'm just misremembering...
