Nvidia Geforce RTX - performance in arch-viz applications

New Turing (Nvidia RTX series) outperforms Pascal (Nvidia 10xx) by 3 to 8 times in path tracing.

Nvidia and partner game development studios have shown wonderful tech demos based on their incoming productions. One of impressive realtime demos comes from "Control" by Remedy:

So it will be a huge thing for game development, but will it be a leap for arch-viz and 3d industry? What will we gain in proffessional 3d applications? Well, it looks like we will gain a lot. The biggest companies in rendering field already stated that they will support RTX technology in their products, as it provides significant speed gain during rendering and it simplifies the process of getting photorealistic results.

Nvidia RTX cards tested in Evermotion archinterior

• Adobe Dimension CC: Intuitive new 3D creative tool built for all aspects of design and marketing is supporting NVIDIA MDL and demonstrating at SIGGRAPH, for the first time, a preview of a Dimension renderer for NVIDIA RTX ray tracing and Turing GPUs.

• Allegorithmic Project Alchemist: New Substance tool, integrating AI-powered feature with over 100x speedup when running on NVIDIA Turing GPUs compared with CPUs. Has been presented at Substance Days at SIGGRAPH this morning, and will be shown in the Allegorithmic booth.

• Allegorithmic Substance Designer: Worldwide reference material editor, integrating RTX through DXR for light baking. RTX gives a speed increase of 800 percent compared with previous CPU-based technology.

• Altair Thea Render: New SketchUp and Cinema 4D plugins, along with the upcoming Rhino plugin release, will help a broad range of markets get a ray-tracing performance boost by one order of magnitude using NVIDIA OptiX denoiser technology.

• ANSYS Optis VRXPERIENCE and Speos: Simulation software leveraging NVIDIA OptiX for faster convergence and high framerate deterministic ray-traced simulation for complex optical system, with 30x speedup compared with CPU legacy technology.

• Autodesk Arnold: The Arnold GPU, which is currently in beta, is one of the first production renderers to utilize NVIDIA OptiX. At SIGGRAPH this week, we’re previewing it running on our latest Turing GPU hardware, featuring ray-tracing hardware designed specifically for OptiX.

• Blackmagic DaVinci Resolve: World’s most popular color-grading application, using Turing Tensor Cores in Resolve 15 to accelerate AI inferencing for graphics enhancement.

• Blender Cycles: Open source renderer using NVIDIA CUDA to accelerate performance.

• Cebas finalRender: GPU-accelerated ray tracer for Autodesk 3ds Max uses NVIDIA OptiX AI denoiser for 5x+ acceleration.

• Chaos Group: Preview of Project Lavina using Microsoft’s DXR to deliver 3-5x real-time ray-tracing performance over Volta generation for scenes exported from Autodesk 3ds Max and Maya. VRAY GPU using RT Cores in Quadro RTX for substantial acceleration over NVIDIA Pascal generation.

“DXR on Turing enables us to explore workflows for real-time visualization that were not possible before. We estimate that Turing hardware is 3-5x faster than earlier GPU generations for the real-time ray tracing of our Project Lavina.” — Vlado Koylazov, co-founder and CTO

• Dassault Systèmes SOLIDWORKS Visualize: Visualization tool for 3D CAD data using OptiX denoiser for instant life-like rendering.

• Epic Games’ Unreal Engine: in the future version of engine we  will get NVIDIA RTX technology through DXR to achieve industry-leading real-time ray-tracing performance.

• Isotropix Clarisse: Physically based rendering engine demonstrating OptiX ray-tracing acceleration on Quadro RTX 6000, showing a 20x viewport performance improvement over CPUs.

• Otoy OctaneRender: GPU-accelerated, unbiased, physically correct renderer is demonstrating performance improvements of 5-8x with Octane 2019’s path-tracing kernel — running at 3.2 billion rays/second on NVIDIA Quadro RTX 6000, compared with 400 million rays/second on Quadro P6000.

“NVIDIA RTX ray-tracing hardware is the future – and will define the next decades of GPU rendering. At SIGGRAPH, we’re demonstrating performance improvements of 5-8x with Octane 2019’s path-tracing kernel – running at 3.2 billion rays/second on NVIDIA’s new Quadro RTX 6000 – compared to 400 millions rays/second on P6000” — Jules Urbach, chief executive officer, Otoy

Octane Render 2019 preview shows 4K 60 fps path-tracing (8spp) on Nvidia Quadro RTX.

• Pixar Renderman: Leading film renderer is announcing support for OptiX AI denoiser in R22.1 due later this year. Demonstrating RenderMan XPU architecture that uses CPU and GPU with NVIDIA OptiX.
• Redshift 3.0: Leading biased GPU renderer is announcing that Redshift 3.0 will use OptiX to access RTX ray-tracing acceleration. Redshift 2.6 shipping with OptiX denoising, accelerating interactivity.

Jensen Huang mentioned a 6x performance increase for real time ray tracing. Although this probably does not apply to today's games as those are still fully dependent on the standard CUDA cores (grouped in Turing SM's).
