Update:
Scanline Sync is freaking amazing.
I can confidently say that now after some experimenting and some help from a friend who shared his PUBG RTSS profile where he set up scanline sync for his 1920x1080 monitor, (same game engine so thought I'd try) I can now pan the camera as fast as I want with no tearing at all, and the input lag is exactly the same as when I was just limiting the fps with riva instead of using scanline sync, only it feels even better and easier to aim without the tearing !!! even with max prerendered frames 1 its rock solid and smooth, way better than max prerendered: let 3dapp decide and no scanline sync before !!!!
( I was never bothered by the tearing before since im all about low input lag but seeing the difference now will make it impossible to go back to no scanline sync !)
frametime in the riva OSD is a completely flat line at 8.3 ms 120 fps, and my fortnite has never looked, or felt better, pulled of some kills and flickshots I never was able to do before to be honest earlier tonight lol
for anyone interested here is what I changed in the fortnite game profile in riva tuner folder:
I changed from:
[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
these values might not even be optimal for the game or my setup, but all I can say is its like vsync on but no lag at ALL, if I wave the mouse like a madman then I can almost make out a slight tearline at the top of the screen, but those mouse movements are never used ingame atleast the way I play and have a pretty low sens aswell, and the focus is always in the central portions of the monitor anyway, doing the same thing without scanline sync immediately brings stuttering and tearlines even if subtle when slow mouse movement, less subtle when fast or flicking,
I've been comparing 4 different combinations quite a few times now ingame doing the same actions in the same places on the map and so on, scanline sync disabled + max prerender 1 or max prerender 3dapp decide vs scanline sync enabled + max prerender 1 or max prerender 3dapp decide, and its hilarious how much better it looks and feels with scanline sync + max prerender 1 compared to any other setting, its AMAZING!
monitor again if anyone wonders is asusvg248qe lightboost enabled @ 10% @ 120 hz no vsync @ 1920x1080p
gpu load on my gtx 1060 6gb is around 50% all the time and even with my bottlenecking old shitty i5-3470 cpu and 8gb ddr3ram its rock solid, played this game for a year and was handicapped until now lol, so thats all from me for the moment, just want to say thanks for this forum ! you guys are the best, ill maybe make a new thread just to let people know about this so they can try the same settings if they play pubg/fortnite and want to try scanline sync but are unsure what to put in the profile, maybe this can be a good start atleast for someone
for me it is perfect ! really feels like old quake times with hundreds of fps on my old 150 hz CRT @ 640x480 but way better looking lol!
Cheers !!!
