It does not solve all, it makes it better.
So I made some tests:
Minimum Samples: 512 Pixel Grouping: none
Minimum Samples: 512 Pixel Grouping: none
Minimum Samples: 512 Pixel Grouping: 2 x 2
Minimum Samples: 512 Pixel Grouping: 2 x 2
Minimum Samples: 512 Pixel Grouping: 4 x 4
Minimum Samples: 512 Pixel Grouping: 4 x 4
Minimum Samples: 2048 Pixel Grouping: none
Minimum Samples: 2048 Pixel Grouping: none
Minimum Samples: 2048 Pixel Grouping: 2 x 2
Minimum Samples: 2048 Pixel Grouping: 2 x 2
Minimum Samples: 2048 Pixel Grouping: 4 x 4
Minimum Samples: 2048 Pixel Grouping: 4 x 4
No Adaptive Sampling
