That first one does'nt work, the MTL file is missing...
The second one (blend file) loads fine into blender, with OBJ export,
and opens up with no issues in octane...

I've done a rendering as a comparison.
The GTX285 used for the arion image has 1062 GFLOPS.
My Card has 572 GFLOPS,
so the equivalent on my GPU in rendertime is ~18,5 minutes.
if fryrender actually uses the CPU too it's unfair as i'm not using the CPU, only my GPU.
However a quad core CPU has only ~50 GFLOPS so i don't think you'd actually notice a difference in the image noiselevel with it.

Attached image cooked for 18,5 minutes with pathtracing.

Also, if you examine the fryrender image, it's postprocessed with noise reduction,
you can see it clearly under the window frames (in the dark areas on the right, between the floor and the window frames),
and on the walls, there's a blotchy noise which is the result of a wavelet noise reduction filter.

My image does'nt have noise reduction, it's a pure render.

I also did'nt have the time to set up all the materials etc...
It's a straight import from the blend file, with a few quick tweaks to make the floor and desks a bit less glossy and the chair metal look aluminium like.

Arion also have portal lights on windows judging by sharp shadows.

If arion actually uses portals for this render i will be extremely happy ;)
I rendered it without portals.

Either are portals or some light emitter acting as sun. You can't get such sharp shadows from hdri or skylight alone.

Looks about the same to my untrained eye too...they both look grainy.

I like the overall color tone of the first one better, and the light from the
window looks better to me.

But they both look grainy...why?
