Here’s a small direct comparison with cycles and also with cache.
Using corona benchmark scene from Rawalanche
using single gtx1060!
here’s how 20 minutes of rendering look like using cycles:
here’s 20 minutes with Luxcore (pathtracing only, no cache):
And here’s 3 minute rendering using indirect light caching:
Note that there is currently small brightness difference when using cache, bias isn’t too big but keep in mind it is still alpha version of the software.
I wouldn’t be surprised if in direct comparison luxcore beats even corona, but I cannot test this now.
Luxcore still isn’t as feature complete as cycles for example but development is progressing very fast (this cache solution was probably done in record breaking time :D) I would strongly reccomend to everyone who is doing archviz using blender to give it a try! Also more people testing and giving feedback could accelerate development even more.
I keep track of major features that are being worked on on this trello board if you want to know what is coming to luxcore next:
