Hey rats n chads,
I'd like to share a great video demonstration that tells you how Nvidia Reflex works and what advantage it offers. To most, this is old news, many will have looked all that up by themselves and know what it does, especially pros in the FPS scene are likely to use it in every game that allows it.
But some casual gamers and players who just joined Tarkov this wipe and generally don't game much may have no clue that Nvidia Reflex is now supported in Tarkov, what it does and why it's good to have.
For the TLDR, just watch the video linked below. It explains everything better than I could.
Nvidia Reflex works with your Nvidia GPU to reduce action-reaction latency. From the moment you see that dirty rat on screen and hit the mouse button to the moment your gun actually fires, some milliseconds pass. In the worst case scenario, that is already enough time for the rat to leave your reticle. The result will be a miss. Nvidia Reflex speeds up that process by syncing CPU and GPU to reduce this input latency.
Another important point is the so-called peeker's advantage. It's the difference in latency causing a player swinging around the corner seeing a guy standing behind it way before the guy standing behind it gets to see the peeker. Apart from the ongoing desync issues, this can be a reason for you dying to a guy you don't even see.
Nvidia Reflex can mitigate this problem too, creating better synced screen frames.
Nvidia Reflex does have next to no performance hit whatsoever, so turning it on won't cause any issues even on lower end systems. However, I've seen a few people reporting that their game soft-locked to 60 fps when Reflex was turned on.
Nvidia Reflex can't fix high latency on bad server connections. It won't magically make you hit everything dead-center. And it won't fix that time you hit the mouse button to be greeted by an "unjam your gun" message, followed by an AP round to your temple.
But it can alleviate some of the delays and provide you a greater consistency when roaming Tarkov. Some high end computer screens have computer chips to use Reflex to their full advantage, being able to configure the on-screen scanning and whatnot. But it will also work with a shitty AOC monitor (like I have) and a $10 offbrand mouse.
Generally, the higher the refresh rate of your monitor, the higher the latency boost achieved with Reflex.
Here's a great video demonstrating the difference between Reflex On and Off in direct comparison, highlighting the delay to shoot and the peeker's advantage, using the game "Valorant".
