Some Aerosoft titles are already available for P3Dv4. Thank you for this. I would like to ask if these scenery titles have been exported using P3Dv4 SDK tools? This is because there are some discussions about massive FPS drop when it comes to Dynamic Lighting and certain AA modes.
I hope I am allowed to cite Robert Randazzo (PMDG):
Before you install ANYTHING into Prepar3D v4, you should take the time to research whether the developer merely adjusted their installer to account for Prepar3D v4, or whether the developer actually took the time to re-export BOTH the code elements AND the model elements of a product using the developer/SDK tools that were provided by Lockheed Martin for use with Prepar3D v4.
Through our efforts to trouble shoot user installations that exhibit significant FPS drops when using dynamic lighting, we have found a direct correlation between performance while using dynamic lighting and whether-or-not the scenery was created using the Prepar3D v4 SDK tools. Users who turn on the landing lights in a Prepar3D v4 exported scenery will generally see only a slight performance hit, but if the same user then moves to an airport that was exported using the FSX, FSX-SE or Prepar3D v3 scenery tools- that user will almost always see a significant performance hit. This is to be expected, since the new exporting tools contain many of the programmatic elements needed to allow things like dynamic lighting to work properly with the Prepar3D v4 rendering process.
