GTC: Chaos Group Unveils New GPU Rendering Architecture at GTC 2018

Advances in V-Ray to double the speed of GPU production rendering. Chaos Group makes big announcements at Nvidia’s GPU Technology Conference.


At the Nvidia GTC last week, the V-Ray folks announced an all-new rendering architecture for V-Ray. The new architecture just crushes it, effectively double the speed of rendering for film, broadcast, and design artists.

Redesigned at the Kernel Structure Level

The new architecture is a redesign of V-Ray’s kernel structure, ensuring a dual-blend of high-performance speed and accuracy.

The improvements in performance are so great that the architecture has been renamed from V-Ray RT to V-Ray GPU, establishing the latter as a professional production renderer, now capable of supporting volumetrics, advanced shading, and other smart tech coming to V-Ray Next.

Key Takeaway

Chaos Group redesigned V-Ray’s kernel structure, producing essentially a “new architecture” for GPU based rendering. Compared to a Core i7 processor, new V-Ray GPU on a TITAN V is up to 15x faster than CPU rendering. This is nothing to sneeze at. 

On the Nvidia Titan V, V-Ray GPU is running 80 percent faster than previous benchmarks on the Titan Xp, and up to 10-15x faster than on an Intel Core i7-7700K.

“V-Ray GPU might be the biggest speed leap we’ve ever made,” said Blagovest Taskov, V-Ray GPU lead developer at Chaos Group. “Redesigning V-Ray GPU to be modular makes it much easier for us to exploit the latest GPU architectures and to add functionality without impacting performance. With our greatly expanded feature set, V-Ray GPU can be used in many more production scenarios, from big-budget films to data-heavy architecture projects, while providing more speed than ever before.”

Representing over two years of dedicated R&D, V-Ray GPU builds on nine years of GPU-driven development in V-Ray. New gains for production artists include:

  • Volume Rendering – Fog, smoke, and fire can be rendered with the speed of V-Ray GPU. Compatible with V-Ray Volume Grid which supports OpenVDB, Field3D, and Phoenix FD volume caches.
  • Adaptive Dome Light – Cleaner image-based lighting is now faster and even more accurate.
  • V-Ray Denoising – GPU-accelerated denoising across render elements and animations.
  • NVIDIA AI Denoiser – Fast, real-time denoising based on NVIDIA OptiX AI-accelerated denoising technology.
  • Interface Support – Instant filtering of GPU-supported features always lets artists know what’s available in V-Ray GPU (starting within 3ds Max).

At GTC 2018 Chaos Group hosted a series of talks about V-Ray GPU. We may have more to share about those talks in upcoming reports.

Next Steps

V-Ray GPU will be made available as part of the next update of V-Ray Next for 3ds Max beta, which is coming soon.
