The highlighted features of KlayGE 4.17 are:

Improvements in engine

• New XInput input plugin.
• Add a new component to generate mipmap by GPUs in real time.
• Enable to export skinned mesh from scene.
• Performance optimizations
  • D3D12 plugin is 10% faster than previous version.
  • Use unique_ptr instead of shared_ptr to improve performance when possible。
  • Add a lot of finals and noexcepts to allow compiler to generate better code.

Improvements in engineering

• All 3rd party libraries can be synced from their original git repository, and patching them before building.
• Introduce in C++20 format library.
• Enable to build by clangcl.
• Use modern CMake module to simplify dependencies between projects.

• Reduce the usage of Boost libarary.

Others

• Bug fixes.

KlayGE 4.16

The highlighted features of KlayGE 4.16 are:

Improvements in engine

• Enable to render to multiple viewports in one pass. It’s a solid step for efficient high-quality VR/AR rendering.
• A more convenient way to dynamically switch material.
• Struct support in fxml for building more complicated effects.
• Integrate motion blur effect into deferred rendering framework.
• Support occlusion map in deferred rendering framework.
• New skin rendering algorithm, the performance is 5x of the original one.
• A new memory allocator increases the performane of D3D12 plugin for 5%. It can be further improved in the future.
• Add a com_ptr to improve the efficiency of referencing COM objects, and reduce the binary sizes.
• Use cppwinrt instead of WRL.

Improvements in engineering

• Most 3rd party libraries are synced from their original gir repository, and patching them before building.
• GCC9 support.
• Introduce in C++20 features.
• Introduce GSL in
• Better cross-compiling support.

Others

• Bug fixes.
