Turbo Tools is an addon that simplifies, speeds up and improves rendering quality, automates many compositing tasks, and adds new functionality to Blender. Compatible with all hardware and operating systems that support Blender.  The addon is compatible with Blender versions 2.93 to 4.1 Alpha.

Overview video showing all the main features in under 2.5 minutes:

• Turbo Render – Vastly superior render results in a fraction of the time for both CPU and GPU Cycles rendering. Retains image quality the standard denoisers can’t maintain, in some cases even when providing them with images rendered for 120X longer! For complex scenes you can expect your single frame renders to be reduced from several hours to several minutes! Check out the below video to see how Turbo Render was able to get a gtx 1070 to destroy an rtx 4090!
  
• Temporal Stabilizer – This massive feature provides per pass temporal stabilization, allowing denoising flicker to be removed from animations that otherwise would need hugely longer render times to avoid! Check out the video below to find out how easy and effective it is, and also see the new Temporal Intelligence features added in Turbo Tools version 4 that allow it to tackle even the most complex of animations with both speed and ease.
  
• Turbo Comp – A full compositor suite with real-time playback and compositing directly in the compositor backdrop, branch caching, resaving of file output nodes without re-rendering, automatic file output node creation, publishing of multiple compositions with ease, and lots more.

Examples

Open image denoiser version(left) 1024 samples with noise threshold of 0.01. Turbo version (right) 324 samples with noise threshold 0.1 (ten times more noise). Notice the paint flecks are retained with Turbo, and the skin detail is completely preserved compared to the OIDN blurry results. (right click open images in new tab to see full size image)

Turbo render is able to maintain reflection clarity at extremely low samples. OIDN required over 4 minutes of rendering to achieve a similar quality.

The image is rendered with film set to transparent to produce an alpha channel. The white background (top of the image) is then added in the compositor to highlight the difference in quality. OIDN required a 4 min render to get close to Turbo Render’s 10 second render result, but there was still visible noise (video to follow)

Scene 2 – Indoor scene to test geometry detail and texture detail.

Above we can see that even after 30 minutes of rendering, OIDN is still unable to retain as much texture detail as Turbo Render can at on 1 min!

Even with a 15 second render, that’s a whopping 120x faster than the 30 min render used by OIDN, Turbo Render can still maintain texture detail using it’s ‘Enhanced Textures’ option:

Above we can see that the bottom of the cupboard area is getting quite badly mangled up by OIDN and even worse with OPTIX. This is because denoisers can struggle with dark edges of geometry that meet with shadows due to a lack of contrast. Turbo Render can achieve much better results using it’s ‘slow (all passes mode), even at very low samples (as shown above bottom right).

Notice how turbo render (on the right) has vastly superior image quality when compared to OIDN (left). The most noticeable improvements in this image are the crisp shadows on the notice board and the clarity of the reflections under the desk.
