another post to try help I hope . I've just bought this scenery and I also bought Fly Tampa's Athens . Installed them last night and did a flight from LGAV to LGTS. VAS was around 2.5 at LGAV maxing at around 3 after landing at LGTS.
This was with the NXG. I have FTXG installed , was using ASN for weather and MYtrafficX for AI. I also use REX Essentials plus for textures.
I'll give you my settings, hopefully it may assist in your troubleshooting .
I had LGTS set to lite II after reading this and other threads however may now experiment with default and lite 1, Scenery seemed excellent though at the lite II setting from what I could see from the flight deck on my NGX.
My computer specs are: intel core I5 with a mild o/c to 4000MHz, 8gb Ram paired with a fairly old graphics card, a GeForce GTX460 with 770MB memory using 331.58 drivers and I run win 7 64bit as my operating system.
FSX is running with the acceleration pack and I am running DX10 with Steves DX10 tool.
Only tweaks in FSX.cfg are highmemfix and widescreen
Relevant ASN settings include:
Download interval=5 mins
max cloud layers = 6
Minimum and Maximum cloud draw distance = 60
enhance overcast conditions enabled
haze layer disabled
min surface vis 0miles
max surface vis 40miles
max upper vis 60miles
auto adjust upper vis
relevant fsx settings:
target frame rate locked at 20
anisotropic filtering and anti aliasing ticked
global texture resolution: very high
advance animation ticked
3d cockpit selected
cockpit tooltips ticked
high res 3d cockpit ticked
Level of detail radius : medium
mesh complexity : 100
Mesh resolution: 5m
texture resolution: 7cm
water effects:mid 2.x
land detail textures ticked
scenery complexity : very dense
special effects detail:high
cloud draw distance 60mi
airport veh :none
road veh :none
Rex essential settings:
3d clouds 512x512 (find them just as realistic if not more than 1024X1024)
cirrus clous: 512x512
wave animation dxt1
currently using the "reality" theme in REX
I also use fs2crew ngx button control version whenever im flying the NGX
never really looked at FPS settings during the flight but flight seemed v smooth from take off to touchdown and I also used default ATC for the flight.
I have lots of other pay-ware scenery and add-ons such as the ultimate terrain series and some FTX regions but the only add-on scenery for this region is as I mentioned earlier and all my scenery is active (I may look at the scenery config editor for enabling and disabling scenery, looks interesting)
I hope this helps you troubleshoot and get you up and running with this scenery.
If I've missed anything relevant out or you want to know more about my set up please ask.
