Re: Luxcore is very slow and freezes

the kernel compilation happens every time I switch to rendered view? I don't know why but it's still laggy, the shading process is very difficult and sometimes it freezes. I can barely guess how hard can be develope a render engine, mine are not complainings but feedback to develpe a strong and powe...

Re: Luxcore is very slow and freezes

I've deleted the next lines to stay in the allowed character Hm, this is where it gets interesting. Can you make another post with that part of the log? it's basically a repetition of the last few lines, like this, many many times, until 10 seconds of preview are over: get_changes(): checking for c...

Re: Luxcore is very slow and freezes

with the latest version the selection of the device in the viewport is automatic right? It seems to be even slower, here you can find the complete output of the console, I hope that can be useful: Read prefs: C:\Users\Umby\AppData\Roaming\Blender Foundation\Blender\2.82\config\userpref.blend found b...

Re: Luxcore is very slow and freezes

the only way is to set the viewport render with CPU, it's way less slow but at this point the problem is the intrinsic slowness compared to gpu in ray tracing speed.

Re: Luxcore is very slow and freezes

I guess something went wrong when sending your answer, because all I see is my own quote? Yep, sorry! this happens also with simple scenes (liek suzanne with diff and nrm and hdri light), I'm rendering with GPU but the issue is when working in the viewport. I've updatet my driver but nothing changed.

Are you rendering on CPU or GPU?
Have you tried updating your graphics driver?

Luxcore is very slow and freezes

I really like LuxCore but every time I try to use it for a project it's a pain. It's extremely slow when previewing the render in viewport, everything become laggy, changing almost any parameter and moving the viewport takes years to do. I can't understand why, my pc has an i7 8700K with a GTX 1070T...
