Redshift 3.0.41. RS Principled Hair render test on 2x2080ti+NVLink. RTX ON/OFF

In this video, I am showing a render-test of the new Redshift 3.0.41 on my recent project, which is already familiar to you from my previous tests. Since it has a new Hair Physical Material based on Disney research and I wanted to check how much slower it will render. Why was I already sure it was slower? Because many have already complained at the forum, but also since the material has become physically correct - naturally, it transmits more light and requires big miscalculations. But honestly, I didn't really get into all this .. I'm not a physicist or a mathematician. I am a creator with a creative mindset .. Therefore, for me - if only it renders beautifully and quickly, and what is there in physics and what processes are taking place is not very interesting =)

The release of new NVIDIA Studio drivers also pushed me to this test. After all, Optix 7.2 was added to them, in which they promised to speed up the rendering of hair on RTX.

Showed a variant with CUDA and RTX. But there is clearly something wrong with RTX, since, logically, the scene should be rendered 2-4 times faster, because this happens on ordinary scenes without hair.

The previous test had the same problem and I even wrote about it on the forum -https://www.redshift3d.com/forums/viewthread/33548/

This video is not intended to humiliate other renders. I have already repeated this 100 times and will repeat it again. I'm just interested in checking the performance of different renders in different situations - on my video cards. And it is with my projects. Since I often do hair, this is my main occupation - I show such projects. They are very resource-intensive. As you can see, this scene has consumed almost all 11GB, but thanks to NVLink and "OOC" technologies, it is rendered without problems on the GPU.

And yet - I have no goal of comparing renders. I do not like to do this, because I believe that everyone is good in their own way and each has its own advantages, and I never pay attention to the disadvantages.

Therefore, I record a series of videos - not just comparisons of each of them, but separate tests of each render on certain scenes.
