E-Cycles 2020 based on Bforartists 2 is up to 2.5x faster than Blender OptiX.
It also offers viewport denoising for GTX 9xx, 1xxx and RTX cards. You can choose between the standard(CUDA) or standard + RTX(OptiX) version.
E-Cycles is a very optimized version of Cycles for Windows, Mac and Linux using NVidia's GPUs. You can just hit render and benefit from all the advantages. Render your scenes up to 2.5x
faster out of the box. The Bforartists builds are updated for each official Blender releases. The current one is Blender 2.82 = Bforartists 2.
E-Cycles helps you:
-
save a lot of time by rendering faster. The mean speedup for the path
tracing phase is around 3x out of the box (you can render about 3x more
frames in the same time). It can be up to 20x faster using quality
presets. You can also use the extra speed to render with higher quality
in the same amount of time. Users say it best:
"E-Cycles lets me render & proof huge print ready assets locally on 3 gpus – no renderfarm rt required!" – Paul, CG Artist
- 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
- scene preparation is much faster thanks to optimized BVH building in final render
- 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
- The RTX version requires an Nvidia driver version 436+ and only works on Windows and Linux.
- Requires a GTX 9xx, 1xxx or RTX card.
- Some features are not supported. If you need those, please use regular E-Cycles:
- Volumetrics,
- Branched Path Tracing
- Raytracing nodes (Bevel and AO)
- Baking
- Dithered sobol and adaptive sampling
- first render takes more time due to kernel compilation.
- no CPU+GPU rendering
Support:
Support is only for the E-Cycles parts. Bugs
found in buildbots are to be reported to the Blender Foundation on
developer.blender.org
System Memory:
Scenes have to fit in the GPU memory for
the speed-up to work properly. Since some months, Blender supports
rendering scenes on GPU while using system memory to some extent. While
E-Cycles allows this too, the speed of the system memory is too low and
your GPU will just wait for datas to arrive. In most cases, scenes
requiring more memory than available on the GPU should be rendered on
CPU
