AMD FidelityFX SDK v1.1: FSR 3.1 Support and Decoupled Frame-Generation

AMD has just unveiled the FidelityFX SDK v1.1, packed with exciting features for gamers and developers. Let’s dive into the key highlights:

1. FSR 3.1: Enhanced Upscaling Quality

What is FSR 3.1? FSR (FidelityFX Super Resolution) 3.1 is an upgraded version of the FSR 3 upscaler. It delivers increased image quality with fewer artifacts and less temporal instability.
New Features: FSR 3.1 now supports direct letterboxing and improves quality for excluded items from reactive mask inputs.
Decoupled Frame Generation: Unlike before, FSR frame generation is no longer tied to upscaling. Developers can use FSR frame generation with third-party solutions like NVIDIA’s DLSS and Intel’s XeSS.

Minimum FPS: For an optimal gaming experience, aim for a minimum of ~60 FPS before applying frame generation.
Graphics Settings: Adjust game settings, resolution, and upscaling quality modes based on your hardware capabilities.
AMD FreeSync: Enable AMD FreeSync if you have a compatible display.
Windows 11 Users: Enable Hardware-Accelerated GPU Scheduling (HAGS) under Windows settings.
Anti-Lag Considerations: Disable AMD Radeon Anti-Lag to avoid frame pacing issues.
Avoid Fluid Motion Frames: Don’t combine FSR frame generation with AMD Fluid Motion Frames.

Vulkan Support: FSR 3.1 now works seamlessly with Vulkan API.
Unreal Engine Compatibility: Updated FSR 3 plugin for Unreal Engine v3.1 and support for Unreal Engine 5.4.
Brixelizer: AMD introduces Brixelizer, an alternative to ray tracing for lower-end GPUs. Faster performance with similar image quality.
- Tips for Brixelizer: Increase voxel size, manage ray tracing costs, and optimize mesh assets.

Developers can track GPU workloads and create reports using AMD FidelityFX Breadcrumbs library.
