It is really terrible :roll:

50% is due to some huge hardware limit but the other 50% is, hand down, their fault. This looks like the first Intel real-time on CPU ray-tracing demos released many years ago... they were terrible too (and we know how it ended). I wonder why they never learn.

P.S. NVIDIA, at least, hires people with CGI experience and they fight with current hardware limits trying to deliver a decent result.

Are theses two tech compatible with GPU ?

Cool sky model, with features like earth's shadow taken into account.

Accelerated Light-Transport Simulation using Neural Networks

Neural network-based techniques have taken many fields by storm, but until recently have seen relatively little use in the field of physically-based rendering. This has begun to change. We'll present techniques for accelerating Monte Carlo integration of light transport without introducing bias by utilizing functions learned by neural networks for variance reduction. Our techniques yield on-par or higher performance than competing machine learning-based techniques at equal sample counts and generalize beyond physically-based rendering, being applicable to other high-dimensional integration problems such as Bayesian inference and reinforcement learning.

Next-Gen Rendering Technology at Pixar

We're continuing on the journey to develop RenderMan XPU, our next-generation photorealistic production rendering technology to deliver the animation and film visual effects of tomorrow. We'll update you on our techniques leveraging heterogeneous compute across CPUs and GPUs, how we adopted the unique features offered by NVIDIA RTX hardware, and how we combine that with our own solutions to make RenderMan the path tracer of choice for so many productions.

Like path guiding is becoming viable for GPUs. but againt it an AI and NVIDIA thing not a very open solution like oidn we can easily add to our Engine quickly. path guiding is something very great for me. It is the next step in term of speed and efficiency we can bring to Luxcore.

Digging in this thread is becoming a pain: what about creating a "Computer Graphics News" sub-forum ? To have a thread for each topic ?
