Examined: How Nvidia Reflex could make you a greater esports gamer


“Frames win video games,” Nvidia likes to say, however there’s extra to esports domination than uncooked body charges. How these frames get delivered issues too. Latency—the time it takes for an on-screen motion to occur after you press a button—reigns supreme within the blink-and-you’re-dead aggressive esports scene. In case your sport appears stunning however feels sluggish, you’ll end up outgunned by rivals enjoying with crummy visible settings to extend responsiveness.

Enter Nvidia Reflex, launched alongside the GeForce RTX 3080 and RTX 3090. When you’ve heard of it earlier than, you most likely affiliate it with low-latency options being added to video games like Name of Obligation: Warzone, Valorant, and Fortnite. However Reflex is definitely Nvidia’s overarching model identify for a variety of recent latency-obsessed instruments. Sure, the Low Latency Mode being added to video games is a part of it, however on Tuesday, Nvidia and its companions are additionally rolling out blisteringly quick 360Hz G-Sync Esports displays with Reflex Latency Analyzer inbuilt. When you’ve invested in suitable equipment, Reflex Latency Analyzer retains tabs on the whole pipeline from the millisecond you click on your mouse to the millisecond the sport renders your gun capturing, serving to you determine which components of your system are performing as a bottleneck.

Nvidia’s Reflex Latency Analyzer and the Reflex Low Latency Mode being launched to main esports video games are two very completely different applied sciences, with two very completely different use circumstances, and maybe two barely completely different audiences. However they’re each centered on the identical underlying objective: making your video games extra responsive. You don’t want one to make use of the opposite. And higher but, Reflex Latency Analyzer’s powers allow us to consider the effectiveness of each, in addition to measure how a lot sooner your reactions could be for those who invested in a pricier graphics card or a excessive refresh charge monitor.

Research have proven that decrease latency can enhance your shot accuracy and kill-to-death ratios in aggressive esports. At this time, we’re going to quantify responsiveness throughout a variety of situations. Buckle up.

Nvidia Reflex Low Latency Mode

First, let’s dig into the Nvidia Reflex Low Latency Mode you might already be seeing within the video games you play. (For brevity, we’ll name the software program SDK “Nvidia Reflex” from right here on out.) When you’re simply interested by uncooked benchmark outcomes for all kinds of situations, contemplate leaping straight to our benchmarking part as an alternative.

Nvidia Reflex is an non-compulsory set of APIs that builders can select to implement of their sport to cut back latency. It really works significantly effectively in closely GPU-bound situations—for those who’re enjoying an esports sport on a higher-resolution monitor, or crank up all the attention sweet, you’ll see essentially the most vital responsiveness enhancements, as you’ll see in our benchmarks part.

How Nvidia Reflex improves latency in video games.

Technically, the Nvidia Reflex SDK works by zeroing out the render queue, permitting the sport engine to inform the CPU to submit render work to the GPU just-in-time. That retains your sport from feeling sluggish. As a result of the CPU isn’t underneath stress to provide a render queue, it might preserve an eye fixed out for mouse clicks till the final doable second, too.

We witnessed Reflex’s elevated click on responsiveness when enjoying Valorant at 60Hz on a GeForce GTX 1660 with visible settings cranked. With Reflex energetic, our mouse delivered a blistering 0.5-millisecond response time throughout 100 clicks, comprised of principally 0.4ms and 0.5ms clicks. With Reflex disabled, it averaged 0.6ms, with principally 0.6ms and 0.7ms clicks. That’s essentially the most noticeable instance, however throughout the board, we witnessed barely higher mouse latency with Reflex on. This explicit profit is perhaps a bit hidden with the mouse we used for testing, although, because the Asus ROG Chakram Core is ludicrously quick. Most mice take a number of milliseconds to register a click on, however this one averages 0.5ms. Sizzling rattling.
