Reducing input lag for FPS Games

[ShoshinUK]

Ok, I am far from an expert on display performance tech.

But I wanted to get some feedback on an idea I have.

I would like to play FPS with the least possible input lag, but stable framerate displayed.

The drivers for wanting this are I suffer sever headache if frames go up and down to much, secondly I find I play better with a stable frame rate.

I am thinking of testing setting my monitor to 60Hz (the min I get across what I play) and enabling NVIDIA Fast Sync. The idea is to push more frames than render on screen, thus reducing input lag? I will prob still limit my upper frames to 90fps so I don't fry my rig (The stuff I play id very demanding on the rig, Squad, Post Scriptum ad Escape from Tarkov etc).

I am fortunate to have some decent gear (in my signature below). Anyone tried this or something similar?

Cheers for sharing any relevant experience.

You want your fps as high as possible with the highest refresh rate possible to reduce input lag. What you are talking about doing would increace it by a significant margin.

@Brooksie359 is the above not true then?

You may well be absolutely correct, I can set my refresh rate of the monitor to the min I can push fps out to in the games I play. But for 90% of the time my rig pushes out much more, I am trying to have a stable frame rate.

For example in Squad my PC can push from 65fps-144 plus fps. I am thinking if I set the monitor to 60hz, run fastsync, but limit my upper FPS (via MSI Afternurner/Riva tuner) to 90fps wouldn't I get the input lag benefit and smooth gameplay with no fluctuations?

just tested and you are very correct, gone back to my usual set 75fps and match refresh rate on monitor - works just fine.
