A variant of DirectX 12’s Sampler Feedback but tailored for Switch’s texture unit. Version 5515 allows a shader to request which mipmap levels were actually sampled, enabling texture streaming decisions without CPU readback.
Memory savings: Up to 40% less texture memory residency in open-world scenes, according to leaked developer notes. nvn api version 5515 exclusive
Memory management gets a massive upgrade in 5515. The new API features dynamic pool resizing, allowing for more efficient VRAM/Heap utilization. Early benchmarks show that heavy workloads now consume up to 20% less memory, preventing bottlenecks in resource-intensive scenarios. A variant of DirectX 12’s Sampler Feedback but
Understanding the exclusive nature requires looking under the hood. Version 5515 introduces several features absent in prior releases. Memory management gets a massive upgrade in 5515
Previous NVN versions allowed asynchronous compute, but 5515 introduces Partitioned Asynchronous Compute. The API can now reserve dedicated slices of the GPU’s streaming multiprocessors (SMs) exclusively for compute queued without any graphics preemption. In practice, this yields a 23% reduction in pixel shader stalls on heavy post-processing workloads.
Exclusive note: The partition scheme requires a runtime lock that only version 5515 provides.
