well right now nV is throwing tons of there people at any Devs willing to step up and put DLSS and RT in there stuff for free

its just email way

at the very lest you guys should look at DLSS since all you have to send nV a copy of the sim to train the AI and nV sends you back to code to add

What developer article are you reading that suggests 64 bits would only be useful for celestial navigation, exactly? Do you have a link? (It sounds like you might be mixing and matching 64-bit address spaces with 64-bit coordinate systems.)

Anyway, I appreciate that you’re asking why we don’t get new tech out as fast as a company that brings in five billion dollars a year…it feels great to be called up to the big leagues!! 🙂

To refine your “solution”, how would you then handle the shadows and reflections of mountains and clouds, for example?

I think, it would not be very convincing to see trees on the shore reflect on water, but no clouds and not the mountains in the distance.

Or think about cloud shadows.

And BTW, “you just don’t render shadows or reflections for that object” is not how ray tracing works.

because they “dont want to get in bed with nvidia” which i think is silly

nvidia would throw money and dev help at LR if they asked for it the catch is LR would have put nv marketing on there product which i dont think that much of draw back

the other issue for the longest time was LR wanted to keep things the same across OS versions but with Apple pulling out of the performance computing world that doesnt mater now

i still think LR should just drop any ideas of supporting Metal and just focus on Vulkan alone with OpenGL as fall back and then Vulkan only for XP12 when that ever happens

the thing is a lot of 3rd party devs dont support there add ons on Mac anyway and not at all on Linux its just not worth the time it takes for 10 people that would be using it

what it looks like nV is doing is you set how far way you want things to be ray traced they showed this in the BF V video where some things far way where not showing reflections at all with RTX on

so there is your solution once you get x meters way you just dont render shadows or reflections for that object which for a flight sim is fine once your up say 1500 feet or so i could care less about shadows on the ground vs when im on approach and right above buildings and trees

tl;dr you can set a clipping plain for how far way you shoot your rays

Thanks Ben for the educational insight.
Indeed that is a realistic see-through into the technology inner-working, as perceived by developers, who really know where wheels meet the rails, in terms of underlying hardware interfacing with the software layer.

The Froblins Demo (reminding of Goblins 1991 from Coktel vision).

In real life, light is similar to an infinite band, in hardware 10 giga rays is still a limited resource which should be wisely spent on target objects based on some filtering criteria, (like you said, aka tessellation), that scales depending on object relative distance to camera.

Yes true, as you have rightly stated:
“Shoot one ray – it will alias as the camera moves and slight camera movements change what leaf you’re hitting. This would result in flickering and shimmering.”
They are relying on tensor AI cores to do the denoising image stabilizer, but the mainstream user do not have any AI – Capable card yet.

I think over the last month, very few people had purchased NV Volta or AMD Instinct, …. maybe a couple of years from now, situation will change.

At best, we hope this new technology to give the airplane interior and airport environment a new depth.

You are doing great to bring the whole engine to the next level.
Keep up the good works
