5 Best ways to Speed up rendering in Blender

As a person who use Blender, I decided to help people with their renders, and in this article, I will show you how to speed up rendering in Blender. All of my methods to make the render faster are what I used to make my render faster, so you may find a better way to make your render faster, and if so, please let us know in the comments section.
This article is intended for blender newbies; if you are a seasoned blender user, you may already be familiar with these methods.

Use CPU+GPU to render your creation

This point may seem extremely straightforward once you’re familiar with the basics of Blender and how to use it in your workstation’s graphics card, but it’s often ignored by first-time users. When you first launch Blender, the option to use your machine’s GPU and CUDA/OptiX is normally disabled.

How to use it.

  • Go to Preference
  • Then system
  • Then use CUDA or OPTEX (use Cuda if you have an old GPU and use Optex for a newer card).
  • Check all the GPUs and CPUs in the list.

Reduce Sample Rate

The number of samples necessary for a good render cannot be predicted in advance; nonetheless, the usual general rule is to use as few samples as possible while maintaining an acceptable level of noise. Keep in mind that receiving fewer samples will have an impact on the final product’s quality, therefore this strategy is best suited for web-only projects rather than ones that need viewing on bigger screens.

Change Tile Size

Changing the tile size might also assist to speed up the rendering process. Reduce the tile size for CPU rendering; however, if you have a GPU, you can utilise larger tiles. You may alter the tile size by X and Y dimensions under the Performance tab, which is also located in the Render Properties panel. The default value is 64×64, while 256×256 is the best tile size when using the GPU, significantly reducing the amount of time the render will take.

Adaptive Sampling

All current versions of Blender have adaptive sampling, which is a significant approach for lowering rendering time. Blender 2.83 debuted Adaptive Sampling last year to minimize rendering times by lowering sample sizes for complicated scenes.

Use Blender 3

As of now, Blender 3 is not released yet, but when it’s come out it will be introducing Cycle X, which is a much faster version of the cycle render engine. Some people have seen up to seven times faster render times in Cycle X.
