Today I flew from KLSE (La Crosse, WI) to KMSN (Madison, WI). Flight was at 3500 ft MSL with features enabled as in my original post. After arriving in KMSN & checking FG memory I found 1.7 GiB. I have 2 GiB installed. Shocked, I decided to repeat exact same flight again but this time remove --enable-skyblend from my .fgfsrc file (wild guess). Same arrival & departure runways, same route (VOR radials), same altitude (3500 ft MSL). Memory footprint was only 639 MiB this time. Weather conditions were the same. Not sure what sky-blend is supposed to do but I do not notice a visual difference with it removed from my .fgfsrc file. ------------------------------------------------------------------------- Take Surveys.
