Some other methods to perhaps speed things up, but also to free up more space in your video cards memory, which may be limited on a laptop or desktop (my old card was a 1050TI with only 4G of VRAM, VERY limited), is to make items in your scene, that are out of you camera's view, not visible. Just click the eye icon in the scene listing so it is not visible. Seems simple enough, but what happens under the hood, on your computer is that all your 3D data is stored on your computers normal memory. When you go to render your scene, all data that is visible, is sent to your video card's memory prior to rendering, this is also the slowest process as the data needs to traverse your system's bus from your system RAM, to your Video card, and that is the slowest process on any PC. When it is not visible, it is not transferred to the video card and is not only faster, but leaves you more video RAM on your video card available for other things you want in your scene that ARE visible. On my old 1050TI, I could not render a scene with THREE characters in it. That was too much data for my small 4G of video RAM (it's why I bought a 3060 with 12G of VRAM). So I managed to fit three characters into a scene (some people on here a while may remember this) by taking one character, who was peeking in a door, and only the upper half of his body visible, and making the parts of his body that were not visible in the scene (hidden by the wall) not visible! I done that A LOT back then, and even HALF a character, with half of it visible, makes a difference! The parts not visible will NOT be loaded onto the video card.Imagine the suffering of someone (as me) that render scenes for hours with only 100-300 iterations, without a graphic card and trash Laptop Specs, just the mercy of the universe. At least I have learned to "Optimize" my scenes...
And of course, hiding ALL items not visible helps as well, so long as they're not REFLECTED by a visible object of course.
