![]() You can set this to Prefer Maximum Performance, to override the power saving feature. The NVIDIA Control Panel has a Power Management Mode option that defaults to Adaptive, allowing the GPU to clock down and save power when the load isn’t high. There is, however, a “hack” of sorts for those who want to squeeze every last microsecond of latency out of the pipeline. Reflex Low Latency mode will automatically take priority over NULL in games that support it. It is recommended that you enable NULL by selecting the Ultra option. NVIDIA Ultra Low Latency mode is still there, to support games that do not support Reflex. The latest GeForce Experience also comes with an automatic performance tuning option, that will turn on low latency options for supported games. Games that support it will enable it by default, if it detects the presence of a compatible NVIDIA graphics card. There is really nothing much to set for NVIDIA Reflex. NVIDIA Reflex : Automatic, With Max Performance Option Call of Duty : Warzone, Black Ops Cold War.It is currently supported on these games : Reflex is only supported by NVIDIA GeForce GTX 900 series graphics cards onwards, using the GeForce Game Ready 457.09 driver or newer. System latency was down by 22% in Apex Legends, and 18% in Valorant. The biggest improvement was seen with Destiny 2 and Fornite – system latency was down by about ⅓. This NVIDIA chart shows the amount of system latency that Reflex shaves off in the first four games to support it. NVIDIA Reflex : How Much System Latency Does It Reduce? This makes NVIDIA Reflex superior to NULL, but only with games that integrate the SDK. ![]() The difference really is this – by integrating with the game, the NVIDIA graphics driver can control the amount of back pressure the CPU receives from the render queue and other later stages of the pipeline. Like NVIDIA Ultra Low Latency (NULL) mode, Reflex prevents the CPU from processing faster than the GPU, eliminating extra frames from being queued up for rendering, which would normally increase render latency. This eliminates the GPU render queue, and reduces CPU back pressure. Once integrated into a game, the Reflex Low Latency Mode adjusts the game engine work to complete “just in time” for rendering. The NVIDIA Reflex Latency Analyzer, which is being integrated into the new 360 Hz G-SYNC Esports monitors, is only eye-candy, and not necessary for Reflex Low Latency Mode to work. NVIDIA Reflex : How Does It Reduce System Latency?Ī careful reading will reveal that the key to this technology is the NVIDIA Reflex SDK – a new set of APIs for game developers.
