which Samples/Pixel (S/p) value did you reach by then? It''s in the statistics line.

say that's X, then you made X * 2560 * 1600 samples in 2147 seconds => Y kS/s which is used as a Lux benchmark for your setup, it''s sort of constant over time, but scene specific.

ref: my i7 990X @ 4.0GHz (12 threads) runs at about 81 kS/s for this luxtime scene.

crosspost - your setup seems to be say 15+ times faster. Not too bad :-)

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
