What is Nvidia Reflex and how to enable it in 2023

Some games also offer a Reflex+Boost setting, which increases the clock speed of your GPU, especially if you are playing games that are CPU intensive, thus preventing any potential bottlenecks.

Reflex can help reduce rendering lag by up to 80% and works best with first-person shooters such as Apex Legends, Valorant, Call of Duty, Fortnite, and others. This is not designed to affect system performance, but there are instances of it having a mild effect on average frame rates. The better response that comes from less input lag should be worth it, though—especially if you’re playing competitively.

To optimize and reduce your system’s latency, Reflex uses a combination of SDK and driver optimizations to effectively remove any bottlenecks between the CPU and GPU. This allows each frame to be rendered by the GPU as soon as the CPU passes it, with no waiting behind existing rendering jobs. The end result can be a dramatic reduction in put lag. Depending on the type of hardware and peripherals you have, you can shave tens of milliseconds off your system latency. This can have a real, tangible effect on your gameplay performance.

It is also possible for game developers to improve game latency performance through additional optimizations.

There are two primary components to the reflex. First up is the Reflex SDK, a set of APIs intended for game developers to reduce and measure rendering latency. Using the SDK, developers can integrate Reflex directly with their games. This allows for latency reduction above and beyond existing driver-only technologies like Nvidia’s Ultra Low Latency Mode.

The second one is Reflex Latency Analyzer which, as the name suggests, is a system latency measurement tool. It is currently available on 360Hz G-Sync esports displays from Acer, Alienware, Asus, and MSI, as well as esports peripherals from Asus, Logitech, Razer, and SteelSeries. This technology can detect incoming clicks from your mouse and then measure the time it takes for the resulting pixels to change on the screen.

Nvidia Reflex can be enabled in individual games by going to your game’s graphics settings. Each game is different, so you may have to search for it, but it should usually be in the options or game settings menu.

here is an example top legends,

After opening the game, select Option button in the bottom right (gear symbol) and then click Adjustment,

Next, choose Video up and down settings advanced, You should see an option to enable Nvidia Reflex.

Some games also have a separate option called nvidia reflex+boost, Enabling this may improve GPU performance to further reduce latency.

There are over 70 games listed to support Nvidia Reflex in some form. Some may only give you latency statistics, others offer support for an auto-configured reflex analyzer, and still others bundle Reflex Low Latency support. Some standouts include Apex Legends, Battlefield 2042, Valorant, Hogwarts Legacy, and upcoming strike back 2 Updates.
