Please refer to thereference documentation.
The rtBufferSetDevicePointer and rtBufferGetDevicePointer interfaces have been modified. The integer encoding of the OptiX version returned by rtGetVersion now includes an extra digit for minor andbugfix versions. DirectX interop support has been removed. rtVariableGetAnnotation is currently not implemented and will return an empty string. Cancelling long running operations with rtContextSetTimeoutCallback is currently not implemented. Writing to attributes outside of anrtPotentialIntersection/rtReportIntersection pair now causes an error. Uninitialized variables in OptiX programs are not allowed, except float, int,uint, programID, and user types. rtContextSetPrintBufferSize must be called before the first launch to take effect. 
Support for automatic paging of data from system memory has been removed.Please refer to the referencedocumentation for details. Some acceleration structure builder mappings and properties have changed.The following functions have been deprecated: rtAccelerationGetDataSize, rtAccelerationGetData,rtAccelerationSetData, rtAccelerationGetTraverser, rtAccelerationSetTraverser, rtBufferCreateForCUDA,rtContextCompile, rtGeometryIsDirty, rtGeometryMarkDirty.Support for Fermi class GPUs has been removed.Reduced host overheadcompared to 3.9 in most scenarios. Improved kernel runtime and compile time performance over 3.9 in many cases.

CUDA interop improvements, including the ability to interop with both the Runtime and the Driver API.Significant performance improvements for local progressive rendering.Reduced host overhead for dynamic scenes.Improved performance with large node graphs.

Streamlined the SDK samples by reducing their number, reducing code complexity, and increasing focus. rtBufferMapEx now implements all map modes, including RT_BUFFER_MAP_WRITE_DISCARD which helps avoidunnecessary device-to-host copies. Improved error checking and validation. OptiX 4.0 can take advantage of multiple GPUs in a system even if they are notof the same architecture. Compiled kernels are now cached in memory, which helps avoid repeated recompiles. With multiple NVLINK-capable GPUs in the system, OptiX 4.0 is able toautomatically and transparently combine their memory, so applications can fit larger scenes. All public OptiX modules and Application/User kernels called by OptiX are visible. Nsight Compute 2019.4 & NsightVSE 2019.3 Debugger OptiX application profiling support. Two new samples included to demonstrate best practices. Decreases memory requirements of large texture sets by only loading required textures. Introduction of demand loaded buffers and textures. 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. NsightVSE can set breakpoints, inspect GPU state, and debug with expected run control through application codeĭownload OptiX™ SDK 6.5 - (Windows and Linux)Windows 7 and higher, 64-bit. All public OptiX module and Application/User kernels called by OptiX are visible. Hit shaders can access triangle vertex data, motion blur data, and the transformation stack. Improved build times (3x to 4x faster on average). 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. 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.
