Re: Gpu rendering on GTX cards broken since Luxcore 2.5

Thanks for your advice Sharly but this problem is not scene dependant and its not affecting the cpu. Its simply that in Luxcore 2.4 my cards rendering in full speed and in 2.5 2.6 not. And The difference in speed is huge. :(

Gpu rendering on GTX cards broken since Luxcore 2.5

Hello. I have done some tests using Gtx 1070ti and Gtx 1660ti and they are working great on Luxcore 2.4 and Blender 2.83. But on Luxcore 2.5 and 2.6 and newest daily build performance drops a lot. Using Gtx 1660ti gpu only rendering using cuda and danish mood scene: Luxcore 2.4 : 2 M samples/second ...

Re: Import Image as Plane issue

Hi. This addon is working only with Cycles and Eevee. But you can use it with cycles first then switch to luxcore and recreate material for the imported image on plane.

Re: How to disable optix rendering for gtx 1070ti?

I Have downloaded Luxcore standalone and with Luxcore Benchmark scene I get 4.6 M samples/second with or without adding the line switching off optix. Its 2M samples/second more than in blendluxore. Basicly my card is twice as fast with LuxcoreUI alone. So it must be something wrong with Blendluxcore...

Re: How to disable optix rendering for gtx 1070ti?

Yes I have moved to Manjaro as I had lots of crashes on windows. Linux is much more stable...no crashes so far. So in Luxcore 2.1 benchmark using only gpu I get about 2.1M samples/second. And on cpu only using all 24 threads I get 2.5M samples/second. Something is seriously wrong here. :?: Cycles-X ...

Re: How to disable optix rendering for gtx 1070ti?

It can be any scene from luxcore demo like Danish Mood. I am getting more more samples per seond from my cpu (ryzen 9 3900x) than from my gtx 1070ti. In Cycles you can use pure Cuda or Optix, when you use optix in GTX series you get slower render times. As Dade said some time ago to me optix should ...
