First, generate a Visual Studio solution for the SDK. The batch file will ask whether to build the SDK as a DLL or a statically linked library, and which samples to include. This generates a build/ directory containing the solution for SDK samples.
For a game that uses Vulkan for rendering (like Red Dead Redemption 2 ), the FSR2 algorithm must be implemented using Vulkan commands, shaders (written in GLSL), and memory management. This is where the vk in our keyword comes into play.
Ensure ffx_fsr2_api_vk_x64.dll is present alongside the main .exe file. 4. Check for vkGetPhysicalDeviceProperties2 Errors ffx fsr2 api vk x64dll work
ffx_fsr2_api_vk_x64.dll (handles Vulkan-specific descriptor sets, pipeline creation, and command buffer dispatching). Required Header Includes
: It handles the logic for taking a lower-resolution input and upscaling it to your monitor's native resolution. Cross-Vendor Support First, generate a Visual Studio solution for the SDK
Understanding the AMD FidelityFX SDK: How to Make ffx_fsr2_api_vk_x64.dll Work
Many mods allow you to replace DLSS with FSR 2. To get it to work: For a game that uses Vulkan for rendering
Before initializing the FSR 2 Vulkan backend, ensure your Vulkan physical device supports these extensions: VK_KHR_get_physical_device_properties2
FfxFsr2Context context; FfxErrorCode error = ffxFsr2ContextCreate(&context, &desc); if (error != FFX_OK) // Check: FFX_ERROR_BACKEND_API_ERROR (Vulkan device mismatch) // Check: FFX_ERROR_INCOMPATIBLE_DRIVER (old GPU/driver)
