I don't normally do interiors so the quality isn't the best, just an old scene I downloaded from a free site ages ago and slightly modified/set up for corona. It has a forest pack rug, and mainly transluscent materials for shades/curtains with a bit of scattering if I remember correctly.
I've set it to render at 1920x1080p with a noise level limit of 1.5% and rendered in corona on 4 machines (dr), then i've changed the renderer to Fstorm, hit the convert scene button, changed the hdri bitmap gamma to 2.2 and enabled direct lighting and then hit "run rt mode" using 1x gtx1070.....oh I also tweaked the lamp shade material a little as it was too see through in Fstorm initially (I may have gone a little too far though as i've robbed the fstorm render of quite a bit of the yellow light.
On corona, I waited until the time remaining had stabilised and was ticking down consistently, but on Fstorm I let it run all the way through to 1.5% noise due to it's time remaining not being as accurate as corona's as it constantly decreases as it renders.
Results attached. Fstorm was still suprisingly favourable still coming in not quite as quick as the outdoor scenes, but still approx 8 times faster. So I definitely think corona should seriously consider having a change of heart on their cpu only stance...with their expertise and team size i'm sure they could match what one guy has been able to do on his own with fstorm.
