> My new MacBook has no problem running at 60 FPS with avg GPU frame time of only 0.95 ms when using clone() or instantiateModelsToScene() on that PG, but using createInstance() I drop to 18 FPS with avg GPU frame time at a whopping 55 ms. astonished

> The issue with instances is only on the latest verson of BJS thou. Running it on version 4.2 the FPS is back up to 60 FPS with GPU frame time at only 3 ms. Switch to the latest version and the FPS is back down to 18 with GPU frame time back up to 55 ms. flushed
