A Look Into Nvidia Reflex
Syncing Your Mouse, Monitor And The Game Engine
One of the new features NVIDIA has rolled out recently, which hasn’t had much press when compared to DLSS and other new or improved technology is NVIDIA Reflex, which is designed to lower the latency between your mouse click and the animation it triggers on screen. The good news is that any card from the GeForce 900 series and on is capable of making use of it, the bad news is that you will need a compatible mouse and monitor to make use of all of the tools associated with Reflex.
Techspot tested the effectiveness of Reflex, with help of two ASUS ROG products, the Chakram Core mouse and the Swift PG259QNR display which are both Reflex Latency Analyzer compatible. That is a tool which allows you to measure the latency between the mouse and the display, showing results with the new GeForce Experience Latency overlay and will let you tweak things to minimize the latency on certain games.
Interestingly this is not a tool for professional gamers to up their game but instead is designed to help the average gamer have a better experience when playing at high resolutions. The testing showed very little effect at 1080p, but if you are playing at 1440p or especially 4K you will see improved synchronization between your mouse and display. You might not feel like spending the time to perfectly tweak the options using the analyzer but simply enabling it in a compatible game will have a positive effect.
The number of game engines which support the feature are rather small at the moment and the process used to lower latency differs between DX11 and DX12, and you can figure out exactly how if you take a peek at the article.
Nvidia is making concerted efforts to expand their GeForce feature set beyond raw performance. Features like DLSS and ray tracing are heavily pushed, and today we'll be checking out whether Reflex is something you should care about.
