Re: Luxcore vs Cycles Final/Viewport

Just applied the same knowledge of adaptive on the porsche scene. small improvement but Cycles is miles ahead. like we miss something in open 3D space.

same time/CPU

Re: Luxcore vs Cycles Final/Viewport

Just doing more test and look like Luxcore convergence can be really affected by poor adaptive settings :

Both are luxcore see how they clearly match cycles convergence quality :

Re: Luxcore vs Cycles Final/Viewport

Another test No caching. just an area light. Max bounce = 4 for both. look how strong lux shadow are while cycles look more softer. Not saying that cycles look better just wondering if this have to do with some kind of trick under the hood ? Luxcore Lux__K.jpg Cycles Cycl__K.jpg File Lux__vs__Cycles...

Re: Luxcore vs Cycles Final/Viewport

I know that viewport engine is RTPATHCPU. So what i mean is that you can easily see that :


1/___Our viewport engine is much slower than Cycles viewport engine

2/___ running for longer with F12 engine show the same speed issue : 10X time render test.

Re: Luxcore vs Cycles Final/Viewport

Does Cycles have Russian Roulette ? Anyway, an analysis must start from simple cases: use a point light and use direct light only (and don't run the test for only 7 seconds or even a microscopic difference in export/start up time can make a huge difference in only 7 seconds). The problem i'm mentio...

Re: Luxcore vs Cycles Final/Viewport

This is a totally different topic, RTPATHCPU is used for view port rendering while PATHCPU is used for final renders. They are 2 different render engines, the first is optimized for fast editing, the second for rendering. He is also comparing RTPATHCPU (i.e. CPU rendering) to "cycles + CUDA" (i.e. ...

Re: Luxcore vs Cycles Final/Viewport

I don’t like to bother asking you the question, what is the meaning of compering clay model renders of different renderers? i make it just simple because it doesn't change very much the story. it make sometime where i had seen this performance issue with Luxcore comparing to cycles. Was just wonder...

Is your area light "invisible" ?
In the current state yes (visible to camera is enable). But even when i set it to invible luxcore converge a lot slower. (The blend file is in the first post if you want to take a look).

Re: Luxcore vs Cycles Final/Viewport

Even With a simple cube Luxcore viewport seem to be way to noisier. Is anyone else experience this issue ?
