>NEVER use v-sync in modern times since it will bottleneck your gpu, fuck up your frame queue, and add input lag
true about the frame lag but that's not because vsync that's because unreal engine's default settings add a ton of frame queuing
you can change the settings in one of the ini files to pretty much remove the input lag
%LOCALAPPDATA%\[GameName]\Saved\Config\Windows\Engine.ini
[/Script/Engine.RendererSettings]
r.FinishCurrentFrame=1
rhi.SyncInterval=1
r.GTSyncType=1 (2 is better if supported)
r.OneFrameThreadLag=0
rhi.SyncSlackMS=10
without vsync you're throwing away partial frames and your GPU has to work way harder plus you get to see tearing
