| Issue | Cause | Solution | | :--- | :--- | :--- | | | Incorrect Motion Vectors | Verify vectors represent previous-to-current screen movement. Ensure velocity is scaled correctly to texture space. | | Shimmering/Pixel Crawl | Jitter Mismatch | Ensure the jitter applied to the camera matrix exactly matches the jitter passed to dispatchDesc . | | Crash on Startup | Vulkan Device Extensions | Ensure VK_EXT_debug_utils or other validation layers are not interfering with the backend's creation. FSR 2 creates pipelines dynamically. | | Black Screen | Resource Barriers | The output resource must be transitioned to UNDEFINED or GENERAL before FSR 2 writes to it. FSR 2 usually handles the transition to SHADER_READ , but verify your engine isn't overriding it. | | DLL Not Found | Dependency Chain | Use a tool like "Dependencies" (modern Dependency Walker) on the vk_x64.dll to ensure it isn't looking for a specific Vulkan-1.dll version or MSVC Runtime that is missing. | ffx fsr2 api vk x64dll portable
You must create an FfxFsr2Context . This context stores the internal state, history buffers, and Vulkan pipeline objects. | | Crash on Startup | Vulkan Device
missing within this DLL, which usually points to outdated GPU drivers or a mismatch between the game version and the Vulkan runtime. developer.nvidia.com Portable and Manual Use FSR 2 usually handles the transition to SHADER_READ
The VK x64 DLL portable solution enables developers to integrate the FFX FSR2 API into their applications, without being tied to a specific platform or device. This flexibility allows for:
