E-Cycles is a very optimized version of Cycles for Windows, Mac and Linux* (2.7x version here https://gum.co/SeYhy) using CUDA GPUs. It's 100% compatible with official Blender, you can just hit render and benefit from all the advantages. Render your scenes 1.5x to 15x faster and spare a lot of money with a much faster CUDA rendering, always using the latest and greatest Blender. With it you get support and weekly builds. The render time for the video above went from 5 minutes to 20seconds on a single 1080Ti. The tutorial is included.
E-Cycles helps you:
- save a lot of time by rendering faster. The mean speedup for the path tracing phase is around 2x out of the box (you can render about 2x more frames in the same time). It can be up to 15x faster using quality presets. You can also use the extra speed to render with higher quality in the same time
- Render very clean preview images thanks to a new AI denoiser that gives great results on still images at 16 samples. Really helpful for quick feedback with your clients
- save tweaking time by using auto tile size and quick quality presets
- keep your hardware on a budget
- spare a lot on your electricity bill thanks to shorter render times
- get more out of your current GPU

Flavio Della Tommasa "Obviously in terms of performance I believe the data speak for themselves. On 8 images, 2h each, I lost a day of calculation. With E-Cycles, in just over 2 hours I solved everything." https://blenderartists.org/t/e-cycles-faster-cuda-rendering/1139717/116
"Impressive speed-ups", "support is good, all issues (specific to E-Cycles build) I have found and reported were quickly fixed" https://blenderartists.org/t/e-cycles-faster-cuda-rendering/1139717/79

About the Author:
My name is Mathieu, I work on Cycles since 2015 (my first patch here https://developer.blender.org/D1530) and already have several patches in official Blender. All the improvements from E-Cycles will be proposed to the Blender Foundation after a year.Is it for me?
If you render at least with a 90€ Cuda card supported by Blender on Windows or Linux, you get this build amortized immediately in most cases (it's often like adding a second card of the same price) and on the long run anyway due to the electricity you spare compared to rendering longer or rendering with more cards. The speedup is for CUDA GPUs during path tracing (when the tiles are drawing on your screen).
For AMD GPUs users, OpenCL is only around 20% faster at the moment and is still being worked on. CPU is like in official Blender. You can still benefit from the new AI denoiser on all platforms. You can see the AI denoiser compared to other ones here https://blenderartists.org/t/e-cycles-faster-rendering-for-cuda-gpus-and-better-ai-denoising/1139717/671?u=bliblubli and here https://blenderartists.org/t/e-cycles-faster-rendering-for-cuda-gpus-and-better-ai-denoising/1139717/503?u=bliblubli or a 7sec render of the BMW scene with AI denoising here https://blenderartists.org/t/e-cycles-faster-rendering-for-cuda-gpus-and-better-ai-denoising/1139717/575?u=bliblubliCan I do only one or two month?
Yes, you stay as long as you want, you are free, and you continue to get updates for the month you have paid.
Do the build work after my Membership finished?
About the 2.8x version
The 2.8x version is based on Blender 2.8, which is still not officially released. Using this build has the same advantages (new features) and inconvenient (less stable and uses more memory than the 2.79 version) as the official 2.80 versions. The support offered with the builds is only for the E-Cycles part. Bugs found in the official version of Blender are to be reported to the Blender Foundation. If you prefer a stable and fast experience, with a huge add-on ecosystem, I recommend to use the 2.79x version of E-Cycles here https://gumroad.com/l/SeYhy. It also has some extra features for fast fly-through visualizations where only the camera moves, especially useful for archviz and product advertising.
Minimum system requirements:
- NVidia Geforce 700 (any card supporting sm_30 which was released in 2013 or more). Latest RTX Cards are supported.
- 64bit Operating system
- drivers supporting Cuda 9 or more.
*The Linux version of Blender is faster as the Windows one in official builds. For E-Cycles, all systems have about the same speed. So the speedup may be relatively smaller on Linux by about 10-20%. It means the mean speedup should be around 1.7x time instead of 2x.
