The AMD Radeon™ Anti-Lag 2 SDK enables games to reduce end-to-end system latency in GPU-bound scenarios on AMD Radeon GPUs.
Download the latest version - v2.0.1
This release adds the following features:
Just released!
Now available as a plugin for Unreal Engine 5.1 and above.
Features
- Reduce latency from input to presented image on GPU-bound games using Microsoft® DirectX® 11 and DirectX® 12.
- Optionally also limit frame rate.
More details can be found in the SDK readme on GitHub and in our Integrating Anti-Lag 2 blog.
We have Naming Guidelines available for use in game user interfaces, including translated strings.
Plugin for Unreal Engine 5.1 and above
Instructions for using the Anti-Lag 2 Unreal Engine plugin:
- Extract the zip file.
- Place the AntiLag2 folder within your Unreal Engine source tree at:
Engine/Plugins/Marketplace - Open UnrealEditor.
- Go to the Plugins window and enable AntiLag2.
- Restart.
- Anti-Lag 2 can be enabled and disabled in the Project Settings > Anti-Lag 2 or via the Console Variable ‘
r.AMD.AntiLag2‘.
More information available as part of the plugin package.
FSR 3 Frame Generation support
The Anti-Lag 2 Unreal Engine plugin integrates with the AMD FidelityFX™ Super Resolution (FSR) 3.1.1 Unreal Engine plugin in order to function correctly with FSR 3 Frame Generation enabled when using the native Direct3D® 12 backend.
Anti-Lag 2 is not compatible with the RHI backend within the FSR 3.1.1 Unreal Engine plugin.
