Okay, I did some experimenting with this, using a simple scene, and rendering it a lot of times...-efbie- wrote: For me it works just as expected
What I found was that "precision" really is the ratio of pixels that do not get sampled compared to those that do. However, sampling very few pixels also gives high rendertimes for some reason, maybe because the few samples need to get extrapolated to the other pixels anyways. In the end, there seems to be an optimum (the lowest rendertime) between about 10 and 20. Anything below OR above that will increase the rendertime several times. I wish the tooltip had told me that before doing that huge render
