Linux and OS X both need full GPU preemption and SMP features like Windows has offered since 2007. Linux also suffers from the issues Apple had with heavy OpenCL and GPU usage. OpenCL news a revamp or we all need to move to Vulkan. I also don’t like to see OpenCL go away, but right now it has problems as it can’t support faster GPU technologies that are only being implemented through Vulkan and DX12. OpenCL was rather good, but even after Apple pushing it, it was a problem for them, as OS X couldn’t handle ubiquitous OpenCL calls through the OS or in several applications. *Except for OS X that is still trying to break/beat Vulkan while also killing support for OpenGL or OpenCL.

Which is why it is important to notice that Microsoft has also been working to help Vulkan use the DXR/WinML technologies – making the technologies fully cross platform.

This might sound more dubious, but remember Microsoft in the 2010s is not Microsoft from the 00s – and even though they had a lot of OSS projects and contributions in the old days, they now are shoving tons of proprietary code out with unrestricted OSS licensing.

nVidia RTX cards are built from Microsoft’s work, and it isn’t exclusive to nVidia at all. The technology nVidia is using in the RTX GPUs is hardware based from Microsoft’s research technologies that were publicly released as DXR technologies for Ray Tracing and WinML(+) for ML/AI in early 2018. These are NOT nVidia specific, even though nVidia uses their CUDA and OPtix technologies in implementation. (See PS5/XBox 2020)Īs for ‘cornering the market’ – RTX features and technologies are already in Vulkan and other full OSS frameworks. However, the base technologies of real-time RT and new AI/ML features are not nVidia’s, and won’t be locked to nVidia – as the next AMD GPUs will have similar hardware support. NVidia is like most other companies, with Intel and AMD also having a history of being horrible. The Blender preferences expose this as a new device type, which lists RTX supported GPUs in the system and supports both single and multi-GPU rendering:

Our approach was to implement a new backend to Cycles which uses the OptiX API to manage acceleration structures plus ray intersection with its programmable parts calling into Cycles’ existing code for ray generation and shading. It provides a complete package with programmable ray generation, intersection and shading while using RT Cores on NVIDIA RTX GPUs for accelerating Bounding Volume Hierarchy (BVH) traversal and ray/triangle intersection testing. NVIDIA OptiX is a domain-specific API designed for accelerating ray tracing. To achieve consistent images across the options, most of the rendering code is shared. What was done?Ĭycles today already supports a range of hardware types, including options for both CPU and GPU rendering.

In this blog, I’ll discuss the technical approach taken, review performance you can expect and share possible a future direction. I’ve provided instructions in the linked review. If you’d like to try it out, the source code is currently undergoing review before being merged and is available for anyone to download, build and run. Now, Cycles can fully utilize available hardware resources to considerably boost rendering performance. To do this, we created a completely new backend for Cycles with NVIDIA OptiX, an application framework for achieving optimal ray tracing performance on NVIDIA RTX GPUs. Over the past few months, NVIDIA worked closely with Blender Institute to deliver a frequent user request: adding hardware-accelerated ray tracing to Cycles.
