What is Nvidia Reflex and how do you enable it in 2023?

In competitive games, sometimes it’s who pulls the trigger first who wins. But sometimes it’s the person who’s PC reacts fastest. Finding out just what kind of input lag you’re dealing with is the first step to eliminating it, and Nvidia Reflex is a great tool for the job. In some games, it can even go further than measuring latency — it can help reduce it.

Once you have a high-performance gaming CPU and a powerful graphics card, the best way to make your PC more suited to competitive play is to shave off a few milliseconds in input lag. Here’s how to use Nvidia Reflex to do just that.

It might even give you a competitive advantage.

What is Nvidia Reflex?

Nvidia Reflex is a suite of GPU, G-Sync display, and software technologies that help in measuring and reducing system latency. By doing so, it allows the PC and the display to respond faster to mouse and keyboard inputs, essentially allowing you to target and kill enemies faster and with greater precision.

Just like Depp Learning Super Sampling, Reflex Low Latency mode is a proprietary technology that requires a Nvidia graphics card. While having a recent GPU like one of the RTX 30-series, ensures the best experience, Reflex can work with any model, including the GTX 900 and above. It works by optimizing the GPU and the game to provide you with the low-latency best performance.

Certain games also offer a Reflex+Boost setting, which increases your GPU’s clock speeds, especially if you are playing games that are CPU intensive, thus preventing any potential bottlenecks.

How does Reflex work?

Reflex can help lower rendering lag by as much as 80% and works best with first-person shooters like Apex Legends, Valorant, Call of Duty, Fortnite, and others. It isn’t designed to affect system performance, but there have been some instances of it having a mild impact on average frame rates. The improved responsiveness that comes from a reduced input lag, however, should be well worth it — especially if you’re playing competitively.

To optimize and reduce your system latency, Reflex uses a combination of SDKs 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 along, with no waiting behind existing rendering jobs. The end result can be a dramatic reduction in put lag. Depending on the kind of hardware and peripherals you have, you can shave tens of milliseconds off your system latency. That can have a real, tangible effect on your gameplay performance.

It’s also possible for game developers to improve the game latency performance through additional optimizations.

Nvidia

There are two primary components of Reflex. First is the Reflex SDK, a set of APIs meant for game developers to reduce and measure rendering latency. Using the SDK, developers can integrate Reflex directly with their games. This allows latency reductions above and beyond existing driver-only techniques 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 tech can detect clicks coming from your mouse and then measure the time it takes for the resulting pixels to change on the screen.

How to enable Nvidia Reflex

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

Here’s an example of Apex Legends:

Next, select the Video settings on the top, and under Advanced, you should see the option to enable Nvidia Reflex.

Some games also have a separate option called Nvidia Reflex+Boost. Enabling it can improve GPU performance to further reduce latency.

What games support Nvidia Reflex?

There are over 70 games that are listed to support Nvidia Reflex in some form. Some can only give you latency stats, others offer support for the auto-configured Reflex analyzer, and another bunch support Reflex Low Latency. Some standouts include Apex Legends, Battlefield 2042, Valorant, Hogwarts Legacy, and the upcoming Counter-Strike 2 update.

More games are being added all the time, so keep an eye on the full list on Nvidia’s website for the latest releases.
