Imaginesim have repackaged their latest release and it now contains both FSX and Prepar3D versions.
ATL by definition is a monumentally busy place. It's the World's Number 1 whether by passenger traffic, landings and take-offs, revenue flights, aircraft movements, daily ops, non-stop flights, the superlatives go on.... 96 million passengers board nearly 1 million flights to over 200 destinations every year. There are 7 enormous terminal concourses and almost 300 aircraft parking ramps spread across 4,700 acres.
Despite it's enormous size and complexity they have striven to make this airport accessible to everyone. With the built-in multiple-option configuration tool it is extensively optimizable, making it suitable for all types of computer specifications. For those of you with high-end superfast computers there's an optional 'Hi-Spec' pack adding in tons of extra detail. If your PC is getting on a bit then you can take advantage of the 'Lo-Spec' pack that swaps in files that are kinder to your GPU. If you've already got the FSX version you get the Prepar3D version for free.
