![]() One issue we found is that in GPU rendering, if only a small subset of the whole image is slow to render (like a character’s hair) then GPU occupancy would be low. While most benchmark scenes were rendering faster with Cycles X, a few involving many layers of transparent hair were showing performance regressions compared to 2.93. Since then we have restored volume rendering, and found that GPU rendering performance improved 3-5x in various volume scenes. For details, see the GPU kernel documentation and GPU performance development tasks.Īt the time of the initial announcement there was no volume rendering support. This is an accumulation of many incremental changes. Render time on an NVIDIA Quadro RTX A6000 with OptiX GPU rendering performance has been further improved. Well give a quick overview of recent developments. Since the announcement, developers have been working to complete and stabilize the code, as well add new features and improve performance. ![]() The rendering improvements from the Cycles X project will be in the upcoming Blender 3.0 release.
