Please visit https://developer.nvidia.com/optix for more information and the download link for the new OptiX 4.1.1 and previous releases.
Improvements to 4.1.1
- Reduced host memory usage for scenes with large numbers of geometry instances.
- Fixed a bug where the primitive index offset was ignored if a GeometryGroup only contained a single GeometryInstance.
- Fixed a bug in Optix Prime where the least significant bit of the floating point hit distance could be non deterministic for some triangles in a scene, depending on their location in the Bvh.
- Changed all Optix Prime SDK samples to use CUDA context by default.
- Fix for scene creation time when sharing Material across many GeometryInstances.
- Fixed a memory leak on GL interop buffer destroy
- Fixed an issue where the CUDA compute cache would sometimes not kick in, causing longer compile times.
- Updated installer framework to avoid security problem at installation time of the SDK.
If you’re setting up a new development environment for OptiX, please find the list of prerequisites and supported combinations of host compilers and CUDA Toolkits inside the OptiX Release Notes on the download site.
