- Optimize PMJ pattern generation, and generate more samples
Addressed in Cycles X:
- Denoising can detect patterns due to adaptive sampling only working per tile. (T79190)
- Solve issues with combined CPU and GPU not using the same amount of samples. Possibly by using a higher adaptive step for both CPU and GPU.
- Render multiple small times at the same time for GPU, to allow adaptive sampling to stop and match CPU without too much performance impact.
