I cant say how well the feature might really work without trying it, but if Nvidias video demonstration is to be thought, it may only be noticeable to an expert gamer who can feel the microsecond distinction in latency. Nvidia does recommend that in some cases, that little difference might dramatically alter the outcome. According to Nvidias demo, enabling Reflex could be the difference in between a critical hit and missing completely.
Your mileage may vary, however if you have a Nvidia graphics card– Reflex works on cards as old as the GTX 900-series– and a G-Sync monitor, you ought to be able to provide the low latency feature a shot. Allowing Reflex needs the latest version of Nvidias drivers and an updated copy of whatever game you desire to use it in.
Nvidia is launching its latency-reducing tech, Reflex, for anybody who has a Nvidia graphics card and plays the PC version of Overwatch. The company evaluated the feature in Overwatchs PTR servers in March, and now Reflex is live and theoretically readily available for competitive play. Nvidia declares Reflex lowers the time between pulling the trigger in Overwatch and the video game rendering the shot on screen by as much as 50 percent, and now you can quickly evaluate that.
Latency can be triggered by a variety of things (web speed can be a big factor in competitive play) however Reflex is focused on reducing latency triggered by computer system hardware. The longer the delay in between a click and the video game responding, the much better opportunity whatever the gamer was reacting to is currently out of frame. In this case, Nvidias tech isnt brand-new, and Overwatch is just the current esports title to be totally contributed to the little collection of 15 games that support Reflex so far.
