The new Radeon Anti-Lag feature in Radeon Software is designed to help reduce input lag in GPU-limited cases. Radeon Anti-Lag controls the pace of the CPU work to make sure it doesn't get too far ahead of the GPU, reducing the amount of CPU work queued up. As a result, Radeon Anti-Lag can shrink input lag by almost a full frame, restoring the responsiveness to your game.

Testing conducted by AMD Performance Labs as of June 4th, 2019 on the 8GB Radeon™ RX 5700, using a test system comprising of Intel i7 9700K CPU (3.6 GHz), 16GB DDR4-3200MHz memory, and Windows 10x64 with Radeon Software Adrenalin 2019 Edition 19.7.1. PC manufacturers may vary configurations, yielding different results. With Anti-Lag OFF at 3840x2160p using DX11, Apex Legends (ultra-high preset), Tom Clancy’s The Division 2 (high preset), Dota 2 (maximum preset), Fortnite (high preset), Overwatch (epic preset), PlayerUnknown’s Battleground (ultra-preset), and Tom Clancy’s Rainbow Six Siege had an average input to display latency of 54.6ms, 44.8ms, 22.4ms, 54.4ms, 29.7ms, 48.3ms, 34.1ms, respectively, versus a 36.8ms, 30.2ms, 17.3ms, 35.5ms, 20.5ms, 33.0ms, and 23.6ms latency with Anti-Lag ON, respectively, leading to a 33%, 33%, 23%, 35%, 31%, 32%, and 31% reduction in latency with Anti-Lag ON, respectively. Comparing Anti-Lag ON vs OFF, Anti-Lag reduces average latency by 31%. Performance may vary based on use of latest drivers. RS-295
