After working with the updates and doing some short circuit flights to play around in the scenery, I'm about to release it with one caveat;
Airpark Dallas is actually located west of Hwy. 75 in West Plano, which I will refer to as "Far North Dallas", lol. Leaving Dallas and heading north up 75 you pass through Richardson and then Plano and you would be hard pressed to know when that actually happens as everything is so built up that it all looks the same. Airpark-Dallas therefore is located in a very heavily populated area and especially when taking off to the south you are heading directly into Downtown Dallas with all it's highrise buildings and homes, plus Addison Arpt, Dallas Executive Arpt, Love Field and DFW Airport all within about a 16 mile radius.
I lowered my normally full right settings to about half and removed the grass I had added to the airport in order to get into double digits, but only just (although I will say that it was still flyable and once out of the area everything goes back to normal). So I will upload what I've done and let you decide if your system can handle it or not. The grass is contained in one bgl and can easily be eliminated if you find it necessary to do so. . .normally the small amount I added wouldn't be a problem, but I found it necessary, lol.
I will continue to fly into and out of Airpark-Dallas because between Sherman and Corsicana (all in a corridor north and south of Dallas) I have a total of 6 airports that I've done that I can fly to and that are outside this "Low FPS Zone", lol.
