There is ways to make it faster but you lose some prettyness.
Blender has two render systems.
Cycles = raytraced based rendering. Pros realistic lighting cons very slow rendering
Eevee = game engine style render. Pro fast rendering. Con no realistic lighting and few others.
For few renders I posted, I been using cycles and average time to render the scene was about hour time.
The no saving post I used eevee and the render time was pretty fast like 5 mintues or something like that.
Thank you for your extra dimensional comnent.
