Blender FASTER renders in CYCLES (Denoiser preserves details!)

In #Blender 3.1 #CYCLESX, you can #RENDER a 5 minute-per-frame scene into 33 seconds, using the same graphics card, and the same machine (faster is better)!

If you want to use denoise without losing the detail on the mask or getting weird compression on the de-focused background, this video is for you.
