Same here. There’s 0 difference between having the task manager in focus vs the engine in focus.
(Which makes sense. The engine reduces rendering capabilities but doesn’t unload all content and deallocates space from VRam just because you click out. That would introduce quite silly lag throughout most regular workflows)
It’s using less than 10% of dedicated GPU memory when crashing and happens not when importing but afterwards during the “preparing textures” step.
Even deallocates a few hundred MB from the dedicated GPU memory during the process. Which seems like a bug or some hard coded memory limits for the process.
