Ok, so its the other sceneries that I need to turn off then ?
Everything else not made by FSDT or Flightbeam.
I somehow need to keep below 4GB
You won't save so much by turning off sceneries. If you need to revert to this to be under 4GB, your situation is WAY over what is considered an healthy setup. The things that improve VAS usage the most are:
- Use DX10
- Lower your graphic settings in FSX, especially the "Level of Detail", "Scenery Complexity" and "Autogen Density"
- Don't use HD texture. This won't make a big difference if you use DX10, but if you are stuck with DX9 for some reason, it will be quite effective.
- Consider switching to FSX Steam Edition, which improves VAS usage quite a bit.
