Path tracing rendertime

[Thijsdevries]

Hi guys,

For a project I rendered a few interior images (see image below) with pathtracing kernel with 8000 samples on a Geforce GTX 1070. The rendertime for each frame takes approx 3 hours and still some spots are a bit noisy. On some other topics I saw some users get incredible render results in 20 min. with a GTX 650. What are your experiences with rendertime for interiors and which settings should I change for faster render time.

Thanks in advace
