AMD FidelityFX LPM provides an open source library to easily integrate HDR, and wide gamut tone and gamut mapping into your game.
Supports:
- DirectX®12.
- Vulkan®.
Download the latest version - v1.1
This release adds the following features:
- Vulkan® support.
Features
High dynamic range (HDR)
Highly optimized
Open source, MIT license
- Can be configured to work with any positive RGB input working color space.
- Can be configured to target any RGB output color space (target any display).
- Solution is completely ALU-based without any LUT, so has the capacity to run asynchronously with workloads which are bottlenecked by other hardware limits.
- Supports packed FP16 for better performance on Vulkan®.
Comparison
AMD FidelityFX LPM is highly configurable, allowing you to tweak the numerous parameters to create the look you require.
As seen in Godfall
During the production of Godfall, we continuously fine-tuned the art visuals. We understood our limitations with the current technology, which required everyone to spend an ungodly amount of time to find clever workarounds. Ultimately, we achieved a style that we were mostly happy with, but something was still lacking. We had to take a step back; we needed to figure out why.
Everything looked last gen. The metals were not shiny enough. The armor pieces, the fires, the magical effects, the backgrounds all appeared muted and uninteresting. With little hope and time left to tinker, we thought we had to live with these deficiencies. When AMD approached us with FidelityFX LPM, we were amazed at the potential. Together, AMD and Counterplay worked feverishly to integrate this technology. Not only did FidelityFX LPM bring back the colors and vibrancy we envisioned, but it also helped solidify our goal. The players will now see shiny objects with great detail, bright environments without being overblown, and contrast without muddiness. Above all else, the biggest surprise was the HDR enhancements – the game is beautiful."
