BTW this animation took 300 ++ hours : 12 days to render on ryzen 1700 and 32Gb RAM.
With Corona render and C4D 13 minutes per frame. ( https://youtu.be/0RNpqzuirb4 )

Luxcore has its own character, which I really like. I'm talking about the character of the final image.
This character is like that of a strictly 40-year-old Swiss watchmaker.
No other render is more pleasant.
It would be incredibly shameful to lose that character for the sake of performance.

In the era of the transition from Luxrender 1.7 to Luxcore 2.0, I was looking for a Blender renderer capable of rendering the result as Corona.
Now I see that I have found more.

Yes in fact i was showing how hard animation can be even on paid offline renderer like Corona. 12 Days for just 56 sec of final animation is extreme high.
And no way we want less Quality :mrgreen: :mrgreen: ( saying someone with extremelly poor coding skill :roll: )

Wonder what happen when you let GPT3 improve Luxcore code ;)

1).Let's say we manage to get something Like path guiding speed bump onto GPU resulting in a 6X to 8X speedup.

2).Then Let's say Upscaling become available from Nvidia or AMD or INTEL So here we can get a 4X time speed up using half the original resolution

3).Then you have Something like Nvidia Slow motion AI to render less frame https://youtu.be/MjViy6kyiqs as seen here can result in a 3X speed up.

Let's do the Math : 6X4 = 24 and 24X3 = 72X time speed up. Now let's you have a project where each frame take 20 minute on you 2060S to render without Cache and apply a 72X speed up on it :

20mn in second = 1200 sec
1200 / 72 = 16,66 sec per frame.

4)Let go even further you drop the 2060S for a 3080 you get another 4X speed up : so from 20minute to 16.66 sec now to 5 sec per frames.

Image

Now is all that Realistic ?

Let's take actual solution:

1/Never seen something like that for GPU but there is all that on CPU (and it is where the 8X speeed up came from).But we don't have it now.

Image

2/ Aside from DLSS wich work on raster and DirectX there Ai Gigapixel solution wich work pretty well on image sequence.
Better there is davinci resolve superscale solution but it actually in the non free version :mrgreen:

3/ Never see a Nvidia SDK for Devs about Slow mo but there is Davinci resolve Solution for free : https://youtu.be/GkKdKi6ZLUI

4 Yes the 3080 do exist even if it is hard to pick one atm but it is a question of time. And you can even take 2 of them.


But it is a bunch of IF :mrgreen:
there are for those ai solutions already a lot of good ones (free and opensource)
like rife https://github.com/hzwer/arXiv2020-RIFE for the interpolation of frames
and for upscaling esrgan for stills https://github.com/xinntao/ESRGAN or SOF-VSR for video https://github.com/LongguangWang/SOF-VSR
but are they always worth it they seem perfect on paper but they aren't it would be best for all of those options if you would train them specifically on renders or even modify them to use more data like a depth pass but they will never be as good as a full res render or the full framerate

So basically with this AI you can turn a 5fps video into smooth 60fps rendering. This is a 12X render speed improvement.

Realtime path tracer are closer than we think. At this rate tech like lumen will be outdated so quickly.
