Important Note: Multi-Threading Scenery Processing
Scenery Multi-Threading is a new addition to X-Plane 12.4.0. It will not automatically bring performance improvements to everyone, particularly those who are already GPU limited, or have a weaker CPU. However, it will distribute the workload to process scenery more evenly across the Cores of your CPU and should keep the frame-rate more stable, especially when flying around heavy scenery with lots of objects to draw.
We will release more technical details about that in the near future.
Note: Tobii Eye Tracker 5 Support is for Microsoft Windows Only! For existing users, please remove the Tobii plugin, as it is no-longer needed.
Note: Some plugins like Air Manager will need to be updated
Note: SAM is blacklisted in 12.4.0 due to SDK violations and high crash rates. Please use openSAM as an alternative
Note: For scenery artists, please do not treat the new planter assets as a substitute for global/large-span environments. They are made for smaller airport kerbside planters. Be warned as mis-use does carry a performance penalty!
