Useful hotkeys & tips in this tutorial:
* "CTRL + 1" = Lowest render quality but offers the fastest lit rendering
* "CTRL + 2" = Medium quality
* "CTRL + 3" = High Quality (Slowest)
* "U" Toggles the unlit renderer which has no lighting information but offers significant speed increases
* "SHIFT + S" Toggles stats panel
* "B" Toggles the bounding box preview
* Viewport quality does not affect final export render quality, unless you are using the "Render All" export option instead of "Render".
* "Smooth UI" can be enabled to reduce UI input lag, however it is highly unstable and still experimental
* "Vsync" can cause performance issues
* "Frame Limiter" setting allows you to reduce GPU usage
* If you use more VRAM than available, your simulations will be slow regardless of these other tips.
