OptiX AI denoiser no longer requires redistribution of cuDNN.

Release Highlights NVIDIA® OptiX™ 6.5.0 (Aug 2019) Support for Nsight tools has also been added in this release. The introduction of demand loaded buffers allows faster startup times by permitting launch calls before all textures are loaded and the ability to render scenes with very large texture sets by loading the required textures and mipmap levels to the device as needed. cuDNN is no longer required to use the OptiX Denoiser and all required files are shipped with the driver. The 6.5.0 release of the OptiX SDK introduces many performance improvements and extended functionality.

Improved PTX handling (extended instruction set).

New disk caching features offer flexibility for production environments.

OptiX AI denoiser no longer requires redistribution of cuDNN (included in the driver).

Multi-GPU operation is managed by the application.

#Load textures on demand code

Source code for demand loading library is included and designed for direct inclusion in production applications.

Shader compilation is explicit (Similar to DXR or Vulkan).

GPU launches are explicit and asynchronous using CUDA streams.

GPU memory is managed by the application using CUDA.

Scene graphs, materials, etc., are managed by the application rather than by OptiX Release Highlights NVIDIA® OptiX™ 7.0.0 (Aug 2019) It also includes a library that provides helper functions to load textures on demand. OptiX 7 introduces a new low-level CUDA-centric API giving application developers direct control of memory, compilation, and launches while maintaining the programming model and shader types.

Demand loading source library enables textures to be loaded on demand, which greatly reduces memory requirements, start-up time, and disk I/O compared to preloading textures.ĭownload OptiX™ SDK 7.1 - (Windows and Linux).

For example, it enables debug exceptions automatically, and checks the CUDA stream status for every API call.

Validation mode, when turned on, enables extra safety checks when starting or debugging an OptiX application.

OptiX 7.2 adds the ability to denoise multiple AOV layers simultaneously along with the color image in a single denoising pass.

The OptiX compiler is leveraged to fold constant values and elide complex code that is not required by a particular scene setup.

Specialization is a powerful new feature that allows renderers to maintain generality while increasing performance on specific use cases.

Release Highlights NVIDIA® OptiX™ 7.2.0 (Oct 2020) OptiX 7.2.0 introduces: support for module specializations for runtime feature toggles, Arbitrary Output Variable (AOV) denoising for increased flexibility, improved error checking and debugging for an enhanced developer experience, as well as source libraries and sample code to support demand loading of rendering data. NOTE: Requires NVIDIA R456.71 driver or newer for Windows and 455.28 or newer for Linux. How to get started with OptiX 7 DevBlog
