AMD has added a system latency meter to the latest driver for RDNA 3 graphics cards

AMD has included a new system delay or “system latency” parameter in the preview version of the driver for Radeon graphics cards. It is used to measure the delay between the generation of frames by the game engine and their subsequent rendering by the graphics card. The closest analogue of system lag is the PC Latency Indicator (PCL) for NVIDIA graphics cards.

The new system lag setting only works with graphics cards that support the Anti-Lag+ feature, which is intended to reduce latency. In other words, we are talking only about Radeon RX 7000 graphics card models, as well as “built-in” ones on the RDNA 3 architecture. The function is included in the driver and is active by default. With the new setting, AMD aims to give users a deeper understanding of how the Anti-Lag+ feature, part of FSR3 technology, improves the gaming experience.

Anti-Lag+ technology is an improved version of the original Anti-Lag technology. It provides frame alignment directly in the game code as well as more efficient frame synchronization, resulting in lower latency. It is important to note that the System Delay parameter does not cover all forms of delay. Other technologies such as frame generation may introduce additional delays to the overall gaming experience.

“System lag is the measured delay between the time a game generates a frame and the time the GPU finishes rendering that frame. This doesn’t take into account factors like display latency, which can be further increased by features like advanced sync. Additionally, system latency does not take into account the additional latency of frame generation over AMD Fluid Motion Frames. To view the latter, you can use the metric as part of frame generation. System lag is only available when Radeon Anti-Lag+ is active. In games with Anti-Lag+ that support both DirtectX 11 and DirectX 12, the System Lag option is only available in DirectX 12 launch mode. When using DirectX 11, the System Delay option appears as N/A.“, describes AMD the new metric.

AMD adds that anti-lag controls the speed of the CPU so that it doesn’t run too far ahead of the GPU and doesn’t idle. AMD Radeon Anti-Lag+ technology balances frame rates within the game code itself, ensuring better frame synchronization, resulting in even lower latency and an improved gaming experience.

The Anti-Lag+ function and therefore the system lag option currently only works with the following games: Apex Legends, Overwatch 2, Dying Light 2, Shadow of the Tomb Raider, Rise of the Tomb Raider, Resident Evil 4, Ghostwire: Tokyo, Fortnite, Last of Us: Part I, Star Wars Jedi: Survivor, Resident Evil 3, Borderlands 3. These games must run in DirectX 12 mode.
