Description
  1. Implement a commandlet that renders (with `-AllowCommandletRendering`) and frequently calls `CommandletHelpers::TickEngine()`.
  2. Have the commandlet load a map containing a world-partitioned landscape. The more streaming proxies, the worse the issue.
  3. Capture performance with UnrealInsights and notice that `ALandscape::PrepareTextureResources` is called every tick for every ALandscapeStreamingProxy (in a highly redundant fashion).
