Hello everyone,
I would like to announce that I have finally found the problem and how to fix the issue on all UE4 Games. This fix currently works for Unreal Tournament Pre-Alpha and this fix originally worked for Dead by Daylight. This is something that the software engineers at Epic Games should look into and investigate.
Since it was related to the following issue:https://www.epicgames.com/unrealtour…-investigation
AMD FPS FIX (multicore and flipqueuesize) https://steamcommunity.com/app/38121…7615844128852/
If you have amd “Multicore Rendering” is your enemy. Let it off first.
go to : C:\Users\USERNAME\AppData\Local\NAME_OF_UE4_GAME\Saved\Config\WindowsNoEditor
Open engine.ini as notepad
[/script/engine.engine]
bSmoothFrameRate=false
MinSmoothedFrameRate=5
MaxSmoothedFrameRate=60
bUseVSync=false
bAllowMultiThreadedShaderCompile=false
Turrned off multicore rendering and vsync because multicore rendering cause input lag on AMD.
Now, let’s talk about… ‘‘FlipQueueSize’’ (AMD Graphic Card Only). FlipQueueSize means input register per fps (default 4) and can choose 0-5
Pros: no input lag anygame include desktop
But when u choose zero u feel 30 fps as 100 cause of no input or display lag, i prefer 0
Open > regedit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E968-E325-11CE-BFC1-08002BE10318}\0000\UMD > on right tab “right click > new > binary value > name it FlipQueueSize > enter” then “right click FlipQueueSize > change> 30 00 (if u choose 0)”
If u want more fps also more input lag choose 5 i mean “35 00” (3x 00) x= your choose
