Description

Anyone else noticed significant perf loss in iOS 12 vs 11? Memory usage is up 40% and frames per second significantly lower, but appears to speed up over time.

This is likely not an issue with the mapbox-scenekit code itself - some Googling reveals other iOS developers reporting similar issues with SceneKit in general.

Research direction

No files, tests, or entry points are identified. Start by reproducing the memory and FPS differences on iOS 11 and iOS 12, then profile the SceneKit behavior to separate repository code from the reported platform issue. Done means confirming a repository-specific cause or documenting that the regression is external.
