- All our sceneries works with no issues in P3D V4.
- The more recent ones like KMEM, KCLT and KSDF, has been more optimized for it, with some features using the native P3D SDK.
- No scenery of any developer currently on sale now is made *entirely* for P3D V4. Entirely, means not just recompiled with the P3D4 SDK, but using new features that don't exist in the FSX SDK, like multiple UV channels, material scripting, etc. The first one will probably be our new O'Hare, which will be released sometime in 2018, which is being remade from scratch, with no relationship with FSX anymore.
- Other sceneries will progressively include more and more P3D V4 features, but we cannot comment on how and when right now, and if they will be free or paid upgrades, since nothing has been decided and nothing is in the works right now other than KORD and other new products we already announced (LFSB and KPIT)
