So, with this test I'll stop somewhere here for now =)
If You wish to get Your hands on scene files & play Yourself take a look here: Lounge Chair Free Scene - everything included & You can read a bit more,'bout how & why the scene was setup the way it does.

in adition, had some issues with my PC lately, but rather then testing stability with some artificial stress-test I've put realworld workload trying Daylight animation with Octane Render (version 1.37) - check it out: https://www.youtube.com/watch?v=tMJAPpGIJVs
