Oh my gosh. Thank you so much! There's no way to explain how much this helped me. I went from getting ~5 FPS near the surface of Kerbin, and 3 minute launches taking 15 minutes+, to a solid 20-25 FPS on the surface and 30-40 FPS in space. Now I can launch and not have to look into space to avoid lag!

I'm not sure if there is a maximum speed but all of my landings have been under 40 mps and it works fine. and in the user guide it says to keep your landing speeds aroudn 40 mps or lower. try to land again but try to do it going around 40 mps. are you using the air brake landing system? that makes it easy to keep the speeds low.
