Blender 4.4: Cycles¶
OptiX Denoiser¶
The NVIDIA OptiX denoiser was updated to improve denoising quality. (793918f2b1)
- Improvements in denoising quality can manifest as more consistent denoising, more accurate colours, better retention of detail, and less denoising blotching. In some situations denoising quality can decrease.
- This change only impacts users with older GPU drivers as newer drivers have already switched to this denoiser type internally.

Sample Subset¶
To correctly distribute the blue noise sampling pattern across multiple computers, the sample offset feature has been modified. There is now a Sample Subset toggle with both an Offset and Sampling length. (f09fd9bdef)
Scripts for distributed rendering using this feature need to be updated.
Please refer to the Blender manual for details.
