FreeSync Eliminating Overdrive Inverse Ghosting
Posted: 05 Jul 2019, 14:10
Hey there,
recently I was messing with some setting regarding Input Lag on my Samsung S24E370DL and I've accidentally discovered that when FreeSync was on there was absolutely no Inverse Ghosting with the exact same settings.
I've been playing games with FreeSync on since forever and with unlocked framerates, which isn't rly ideal in terms of input lag especially for FPS multiplayer games, but so wasn't my 4 ms 75 Hz PLS in general, so I never really cared that much, but I was still just curious to see how much Input lag I had and whether I could even notice it without any special equipment/tests.
I thought that the UT movement tutorial starting area would be sufficient enough.
I found that I could indeed sense some noticeable difference with FreeSync On/Off while running with unlocked fps.
What I also [accidentally] noticed while tinkering and switching setting around was that with FreeSync ON there was practically and virtually zero Overshoot/Inverse Ghosting @ any Overdrive level.
I was quite surprised when I discovered that, even more so after I've found other ppl complaining of the exact opposite situation when I tried searching for whether anyone else had a similar experience .

What also seems significant imo, is the fact that FreeSync seems to eliminate the Overshoot even outside it's effective range.
Above 75 Hz/FPS in my case.
I wasn't sure what to make of this and since I couldn't find many ppl talking about this, I've decided to post this in case anyone finds it useful in any way. I'm planing to see whether capping the framerate with RTSS will reduce the input lag, which [theoretically] should be the case.
