• PSA about RTSS's Reflex mode (you might be greatly increasing your latency!)

I think some people are increasing their latency due to confusion about the new Reflex low latency mode in RTSS (software that MSI Afterburner uses). It has to do with how the Reflex setting in a game automatically limits the framerate for you, but the Reflex mode in RTSS evidently doesn't.

For reasons explained by blurbusters in this article, the lowest latency way to play without screen tearing is to limit your framerate just below your monitor's max refresh rate (e.g., 58 fps on a 60 hz monitor or 117 fps on a 120 hz monitor), then turn on gsync and vsync in the Nvidia app (or control panel). This framerate limiting can have a major reduction in latency (see the graphs on page 5 in the above blurbusters article). This is relevant to Nvidia Reflex because it automatically does this framerate limiting for you when you turn that setting on in game (or turn on DLSS frame generation, which uses Reflex). For this reason, it's recommended to turn off other framerate limiters when turning on Reflex (or DLSS frame generation).

This brings me to the new Reflex mode in RTSS that was added in version 7.3.5. It evidently does not automatically limit your framerate just below your monitor's refresh rate. Unlike Reflex low latency mode in a game's settings, you need to set a hard fps limit to get it to do this. If you're not doing this because you think it should work like Reflex when enabled in a game's settings, you may be greatly increasing your latency.

I recently tested this in Returnal on my 120 hz monitor on a gpu (4090) that doesn't have a problem hitting 120+ fps in that game with frame generation and ray tracing off, and DLSS set to quality. Using the overlay that comes with the Nvidia app to measure latency, I tested 3 scenarios (all with gsync and vsync enabled in the Nvidia app, and with RTSS set to use Reflex rather than the previous asych setting):

  • In-game Reflex setting on, RTSS framerate limiter off (set to 0): I got ~117 fps output, and Nvidia's overlay reported ~18-20 ms latency.

  • In-game Reflex setting off, RTSS framerate limiter off (set to 0): I got 120 fps output, and Nvidia's overlay reported ~50 ms latency!

  • In-game Reflex setting off, RTSS framerate limiter set to 177: I got 117 fps output, and Nvidia's overlay reported ~20 ms latency.

That's ~30 ms of added latency from not capping framerate, which I suspect that many people have been doing due to confusion since this new Reflex mode has been added. This new mode is cool. It is compatible with DLSS frame generation, which may be useful if you want to further limit your framerate to reduce power draw or to give you more CPU headroom (which I suspect could lessen certain CPU related stutter). However, it evidently won't automatically limit the framerate for you.

Plus, being on RTSS 7.3.5 or later does not automatically enable Reflex, which is currently not the default (async is). You have to go in the settings to enable it, which most people probably haven't done.

I found a formula to remove number from a text strings in excel. Here is the formula: =SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,0,""),1,""),2,""),3,""),4,""),5,""),6,""),7,""),8,""),9,"") i need a way to shorten this.

I had to write the substitute function 10 times. Is there a function that can repeat this formula 10 times changing only one parameter keeping everything same.

Like i write =STITUTE(A1,0,"") then it will automatically repeat the formula changing only the middle parameter. I tried the Rept function but couldn't figure out.
