OptiX 9.1 Release

[dhart]

OptiX 9.1 has been released!

NOTE: support for OptiX 6 based applications has been removed from the driver as of R590. You can continue to use OptiX 6 by using the R580 driver or earlier.

Here are the main highlights from OptiX version 9.1:

• Module creation can now be cancelled midway
• New API enables customizable application-side compile caching
• Added pipeline global variables
• Improved denoiser image quality
• NVRTC support for cooperative vectors
• Several new pipeline options for increased control & build performance

NOTE: there is a new pipeline launch params size setting that is optional in OptiX 9.1, but will become mandatory in the next major version.

NVIDIA OptiX 9.1.0 requires a R590 driver or later.

For your convenience, the OptiX SDK has been made available on Github at this address: https://github.com/NVIDIA/optix-sdk.

For now the SDK will remain available on the NVIDIA Developer site as well, so you can choose whichever download mechanism you prefer. This is separate from the headers-only “optix-dev” repository that’s already on Github. The “optix-sdk” repo contains both headers and samples.

As with the optix-dev repo, all OptiX SDK releases starting from version 7.0 have been tagged and are downloadable, for example: https://github.com/NVIDIA/optix-sdk/releases/tag/v9.1.0

We hope this is helpful, happy tracing!
