    Thank you. It saved my bacon on a homework assignment. Something that would have taken Cycles 12-15 hours to render was only a fraction of that with comparable results.

    Using 2.92 and 2.93 versions and very nice speeds, comparable to E-cycles. In my 12 hours or so with k cycles I found it very stable with many add-ons enabled. Teamed this up with SID denoiser and I can get some very low sample renders very fast that look great. I get instant crashes with 3.0 using the viewport bloom, but this is probably due to my hardware it doesn't like vanilla 3.0 much either, developer said he'll be bringing bloom to 2.92 and 2.93 soon so I'm sure that will clear up the issue.

    K-Cycles worked for me just like advertised. Developer was quick to answer any questions I had and with future updates this is an easy to recommend product.

    It's much faster and has much less waiting time to see the results.
    There are many GPUs that support it, which is great.

      Thank you for noticing K-Cycles speed. K-Cycles was tested extensively in beta with all type of Nvidia graphic cards it render properly with great performance and image quality. I give direct support or we have discord channel with general information and support with specific issue with K-Cycles.

    The creator of this addon is awesome and got back to me very quickly! Not to mention took the time to help resolve some questions and was very thorough. I'm really enjoying using this so far as I was midway through a project when I saw this release, and decided to give it a shot. Now my frames are rendering twice as fast and cleaner than before! Huge time saver thanks Ethan!

    does not render my heavy scenes unlike stock cycles and e-cycles, e-cycles crashes sometimes but this one does not work when you are on the edge of your video memory, i hope it can handle big scene in the future. nice perf though with the fastest setting when you smaller scene even with volumetrics.

      I have done many heavy archviz scenes without any problems. The important factor is that it needs enough GPU memory for the scene and textures to fit and render. If their is not enough GPU memory, regular Cycles would run into GPU errors.

    Reconsider if you render scenes with hair/fur. I found K-Cycles to be around 5-15% slower than original Cycles in this case. Using default settings and tested on 5 different scenes.

      Not all type of scenes are going to get big improvements and the benchmarks graph show that. Test with some of public available scenes from the benchmark and K-Cycles should be faster. Their many issues affecting performance in Cycles. I will be glad to take a look at your problem scenes to figure out performance issue.
