I purchased this scenery couple months ago. It ran poorly fps wise and for lacking a lot of definition I was surprised. Yes I'm running Orbx TE Britain but I run big airports from orbx without big issues except for eglc. I have since uninstalled it and use the previous freeware version which to me looks good enough. If it gets a big upgrade I will try it again. Wished UK2000 made XP11 version.
When taxiing to 8L I noticed the two roads that I crossed over where not 3D and the vehicles were riding through the 2 taxiways . Taxiways N1 and N2. All the other roads and taxiways were fine. Otherwise this scenery rocks like the rest of your stuff.
