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
Luxcore 2.5 and 2.6: 56 K !!! samples/second
So question to the devs what is causing such a drop in performance in newer versions of Luxcore?

Re: Gpu rendering on GTX cards broken since Luxcore 2.5
I don't Know but try this :
1__ Make things simple by create a new simple scene to check you don't even need material.
viewtopic.php?f=4&t=4277 try this simple scene for example
2__ Try to confirm if this affect CPU to
3__ try to have the lastest driver for your GPU.
4__ Does it happen with caches enables or even without them ?

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.

Re: Gpu rendering on GTX cards broken since Luxcore 2.5
I have a card similar to yours, and using Blender 3.1.2 and Luxcore 2.61 I have here rendering 4.9 million samples per second.
It must be something in your system.
I'm using windows 11

Its weird as its happening on 2 systems, laptop with gtx 1660ti with windows 11 and Linux and windows desktop with gtx 1070ti all with updated drivers.

Re: Gpu rendering on GTX cards broken since Luxcore 2.5
Also In luxmark 3.1 hotel scene I am getting 3.5 M samples/second on gtx 1660ti.
So Luxmark is working ok and luxcore in blender not...
