, essential for compiling shaders that run efficiently on the Tegra Pascal and Ampere architectures. DLSS and Ray Tracing Foundation:
: Harness the specific power-draw and clock-speed capabilities of the Switch's custom Tegra chip. NVAPI - Get Started - NVIDIA Developer nvn api version 5515 exclusive
Historically, NVN required shaders to be compiled offline and stored as part of the executable. changes this by allowing Direct Shader Extension loading via memory-mapped I/O. Developers can now patch or load new shader binaries at runtime without reloading the entire graphics context. This is critical for adaptive resolution upscaling and moddable rendering pipelines. , essential for compiling shaders that run efficiently
We put API 5515 to the test against its predecessor in a controlled environment. The results speak for themselves: changes this by allowing Direct Shader Extension loading
In a test scene with 10,000 grass blades (similar to Breath of the Wild ’s Hyrule Field), draw call overhead dropped by 34% when using 5515’s indirect count method.
Evidence suggests:
