QMC optimized | Oversampling in different Scenarios, low detail

Let me give you a summary of the different scenarios comparing rendertimes between a rendering that used no oversampling and an optimized rendering using oversampling. The optimized version was determined earlier by testing out 5 settings that had shown most promise. The ratios between samplecount and oversampling were generated by applying our rule of thumb to achieve a comparable quality to that of the unoptimized rendering.

(sorry for the gif-parade readers..I know it's not very convenient. Embedding quicktime would be nice if apple finally manages to fix the 64bit bug within browsers)

So what's the bottom line here?
Using oversampling we could achieve a decrease in rendertime down to between 7 and 75%.

The manual suggests the smaller the lights the bigger the oversampling ratio should be. I can only confirm this on some of my scenarios. Values between 2 and 16 seem reasonable which would be less than weak to medium if you'd  pick the rate from the presets. I never had to go above medium on my seven scenarios. If you should come across a suitable scene for high oversampling rates please let me know. :-)


Next we're going to take a look at the same scenarios with and without oversampling only this time with some heavy details in the scene.
