Ehm, it's never getting to 2Gb of memory used. Sometimes it crashes at 1.5Gb used, sometimes at 900Mb used. I have default scenery, no custom scenery at all. Default aircraft only, CRJ-200 is the only one custom aircraft i have installed. Lowest possible settings. Really, there is a button in X-Plane render settings that says "put all settings to max speed", that's what i've done. I can't decrease the aircraft amount around me, as it's already at minimum. And i don't fly at busy areas where is a lot of aircrafts around (like Munich or Madrid). I fly around Alicante and Valencia. I'm sure CRJ-200 is heavy textured and CPU required aircraft. It's just strange that it doesn't happen to anyone else, just me. Can fly online with default aircrafts almost on max settings and can't fly good one with lowest settings so sad So i guess i have to get X-Plane 9 to enjoy this beauty. Btw waiting your 777. Hopefully it will work better.
