How To Speed Up View port Rendering In Blender 2.9 2.91 | Speed Up Cycles | Render Cycles Faster
There are several ways to speed up viewport rendering and Cycles rendering in Blender. Here are some tips to help you achieve faster rendering times:

Reduce the number of polygons: High-polygon models can slow down your viewport rendering and Cycles rendering. To speed things up, try reducing the number of polygons in your scene. You can do this by using Blender's Decimate modifier or by simplifying your models manually.

Use low-resolution textures: High-resolution textures can also slow down your rendering. Try using lower resolution textures or scaling them down to reduce the amount of memory needed for rendering.

Use Simplify settings: In the Render properties, under Simplify, you can adjust settings such as Max Subdivision and Viewport Simplification to optimize the render speed while still keeping the overall quality of your scene.

Use GPU rendering: If your computer has a good graphics card, consider using GPU rendering instead of CPU rendering. GPU rendering can be much faster, especially when using CUDA or OpenCL.

Use denoising: Blender's built-in denoising feature can help reduce the amount of time needed for rendering. By using denoising, you can achieve similar results to a higher sample count without needing to increase the sample count.

Optimize lighting: Complex lighting setups can also slow down rendering times. Consider simplifying your lighting setup or using simpler light sources, such as point or sun lamps.

Use the right sampling settings: Adjusting the sampling settings can significantly impact your render time. Increasing the number of samples can improve the overall quality of the render, but it will also increase the rendering time. Start with lower sample counts and gradually increase them until you get the desired quality.

By following these tips, you can speed up your viewport rendering and Cycles rendering in Blender 2.9 and 2.91, and achieve faster rendering times without sacrificing quality.

Impressive. Just learned about turning down light paths. My renders are much faster now.

Dude, don't lie. This is crap. You say how to speed up viewport rendering, and then you even change to 100 samples for some reason. THEN you enable denoise? Denoise is faster to get a good looking result, it's not faster rendering. The title should be "how to see a decent image faster in the viewport by enabling denoise." You aren't speeding up anything. If you still need 32 samples, you actually made is Slower.
