If you all are talking about the time span when that "Loading" image shows up in the right lower corner of the screen, there is a huge noticeable difference between 0.20 and 0.21 I have both installed and was just playing with 0.20 earlier this evening when I decided to see if there was an update, there obviously was so I installed that and tried it and there is a most noticeable difference in how long it takes to switch between "scenes" if that's what you're calling them, i.e. build center, launch pad, radar facility etc. It's not bothering as I feel confident they'll lower the time again like it used to be and it certainly won't keep me from playing around with 0.21
