Memory bandwidth is the perennial bottleneck on mobile-class GPUs. NVN 5515 debuts TMC 2.0, which adaptively compresses render targets using a hybrid of delta and pattern-based compression on-the-fly. Unlike the original TMC, version 5515’s algorithm does not fall back to uncompressed storage when facing high-frequency detail; it instead uses a "sparse rewrite" method.

The API was built to provide direct, "close-to-the-metal" access to the Switch's Maxwell-based GPU. Its "exclusive" features allow developers to: Nintendo Independent Wiki Alliance Maximize Efficiency
Games using temporal upscaling (like Tears of the Kingdom ’s FSR 1.0 hack) can reduce tile memory during heavy particle effects, freeing bandwidth for AI or physics. Unlike the original TMC, version 5515’s algorithm does
The is a proprietary, low-level graphics API developed by NVIDIA exclusively for the Nintendo Switch ecosystem. While standard cross-platform APIs like Vulkan and OpenGL 4.5 are supported on the console, NVN is the primary choice for first-party and high-performance third-party titles because it is highly optimized for the Tegra X1 hardware. Overview of NVN API Version 55.15
With version 5515 , we are likely seeing the beginning of a for Switch 2. While the original Switch supported Vulkan as a secondary option for porting ease, the "exclusive" nature of version 5515 suggests that some of the most graphically intensive games will bypass Vulkan entirely and run only on this proprietary NVN layer to achieve maximum performance.
Fewer CPU cycles wasted on rendering commands.
