Scanline sync is AMAZING !
Posted: 17 Jan 2019, 03:00
Just wanted to share my experience and results after some experimenting and help from a friend who plays a lot of PUBG, and I play a lot of Fortnite, I wanted to try out scanline sync but couldnt figure out what values to put in rtss and what to put in the rtss fortnite game profile, so my friend sent me his PUBG RTSS profile and I just copied everything in the [Framerate] section to my own fortnite profile and tried it out,
the result is incredible, I have to say honestly its crazy !
if anyone plays fortnite or pubg (same engine) you can also try this, maybe it also works for other games, this is for 1920x1080 resolution anyway:
I changed from these, my old profile values: (limiting to 120 fps with rtss and vsync off gave me much better result for some reason than ingame 120 fps limit and vsync off)
[Framerate]
Limit=120
LimitDenominator=1
LimitTime=0
SyncScanline0=0
SyncScanline1=0
SyncPeriods=0
To this:
[Framerate]
Limit=0
LimitDenominator=1
LimitTime=0
SyncDisplay=0
SyncFlush=1
SyncHotkeys=1
SyncScanline0=-180
SyncScanline1=0
SyncTimeout=1
SyncPeriods=0
vsync off ingame and forced off in nvidia drivers, no limit on fps ingame, max prerendered frames 1, this is on a lightboosted asus vg248qe monitor @ 10% lightboost effect, 120 hz @ 1920x1080, the result is 99.99% lack of tearing, input lag same as no vsync , but my aim and vision/clarity and ability to react fast, and precise is so much higher/better now because of no tearing and no stutter! Its like night and day honestly !
gpu load is never more than 50% or so, I play with all quality settings at the lowest anyway except for FXAA enabled in nvidia drivers to remove aliasing a bit, as im bottlenecked by my old i5-3470 cpu but I can imagine if you crank up details and put a heavier load on gpu then there will be tearing, but anyway thats it, those scanline sync values might not even be optimal for the game or my setup but the result is incredible either way,
If anyone is using lightboost/ULMB and playing pubg or fortnite, I urge you to try this! if you are running 1920x1080 like me or even if you play in another resolution you can still copy paste the values and just tweak the scanline values above I would guess, only important thing is vsync off, might even get super good results without lightboost/ULMB its just that im so used to the CRT-like clarity of strobing I will never play without it cant stand motion blur,
anyway thats all I have, just wanted to share this! put those values in your pubg/fortnite RTSS profile (might even be good for other games) disable vsync everywhere, tweak scanline values if needed / other resolution than 1080p, max prerendered frames 1, put unlimited framelimit ingame and see what happens! also try to set game gfx quality settings at some level where your gpu is not heavily loaded, for me its never over 50-60% max what I can see, can use that as a guide perhaps,
anyway back to gaming now it feels like a new game lol feels like playing on a high hz CRT with vsync off only that it looks exactly like vsync on, zero tearing and stutter ! frametime graph is completely flat 99.99% of the time with 120 fps 8.3 ms rock solid
full system specs if interested:
asus vg248qe monitor lightboost enabled @ 10% @ 120 hz 1920x1080
i5-3470 cpu @ 3.5 ghz slight overclock
8gb ddr3 ram
some cheap toshiba SATA SSD drive
evga 1060 gtx 6gb running in "k-mode" with evga precision X OC app (forces boost clocks on core and ram at all times regardless of gpu load)
win 10 1803 with game mode disabled, "disable fullscreen optimizations" ticked in the game.exe, high precision event timer disabled in bios and spectre/meltdown patch disabled aswell with Inspectre app (old cpu so squeezing out everything I can from it lol)
thats it, Cheers !
