Bathroom made of 2.83 blender and rendered with luxcorerender with 1000 samples took 1 hour and 7 minutes Ryzen 7 2700x
Very nice . like you don’t get much benefit from the light cache. should be much faster what is your clamping value and your light cache settings ?
As far as I understand, it is a CPU-only rendering on a 8 cores Ryzen, indeed, a fast GPU can do a huge difference in rendering times.
I’ve a 8700k and the 2700k is faster. Also for this kind of interior and resolution i never exceed 10 min with light cache. If this is without light cache then it make sense.
