from previous frames to create a high-resolution output from a lower-resolution input. Core Functionality & Technical Specs API Backend
To get maximum efficiency out of ffx_fsr2_api_vk_x64.dll , use native 16-bit floating-point math ( FP16 ). This significantly reduces memory bandwidth constraints on modern GPUs. Ensure you compile your SPIR-V shaders with FP16 support and check that VkPhysicalDeviceFloat16Int8FeaturesKHR::shaderFloat16 is enabled on the device. ffx fsr2 api vk x64dll work
