AMD on Monday released Unreal Engine plugins for FidelityFX Super Resolution (FSR) 3.1.3 and AMD Anti-Lag 2 through its GPUOpen initiative. Both plugins support the latest Unreal Engine 5.5, and can be picked up by game developers to integrate with their ongoing projects or be released as updates to their released games. FSR 3.1.3 succeeds the FSR 3.1.1 major release that had introduced Anti-Lag 2 support among a dozen other updates. The latest FSR version adds Unreal Engine 5.5 support, besides a minor update to the way FSR handles UseDistortionTexture commands. Meanwhile, the Anti-Lag 2 plugin for Unreal Engine 5.5 is being released as part of the latest v2.0.2 release of the technology. There are no other changes. AMD FSR 3.1.3 plugin for Unreal Engine 5.5 can be accessed here, and the Anti-Lag 2 plugin for UE 5.5 here.
 
AMD still needs more work in this area in my personal opinion.
