D5 SR (D5 Super Resolution) is a proprietary super-resolution sampling algorithm developed by D5, which combines multi-channel rendering feature maps and utilizes a neural network-based super-resolution image generation algorithm to significantly accelerate the rendering speed of still images.
Enable this option in "widgets" of "Preferences".
Note:
1. This feature does not support outputting exr format at the moment;
2. This feature does not support Intel and AMD series graphics cards at this time;
3. It is not recommended to turn on D5 SR rendering for scenes with post effects such as depth of field and foaming;
4. Image rendering with D5 SR turned on will result in faster rendering while losing some rendering detail.
