Hello there!

I hope I’m in the right section…

I have an issue with unreal editor, my screen flickering all the time and have this « lagging effect ».

Can you help me please ?

This issue appears only with Unreal editor, I don’t have this issue with another programs or games.

This is my config :

Fabricant : Acer

Modèle : Predator PH317 – 52

Processeur : Intel Core i7-8750H CPU @ 2,20GHz

RAM : 16

Systeme 64 bits

Carte graphique

Carte n° 1 : Intel UHD Graphics 630

Carte n° 2 : Nvidia GeForce GTX 1060

I think is due to my graphic cards but I don’t know …

Sorry for my english

Hello,

****** HERE’S FLICKERING FIX *********************

Official 4.25 and 4.26 having some glitches in calculations, namely TemporalAAHistory structure was not filled out correctly

Here’s the only solution that will surely fix for both 4.25 and 4.26 versions (building from the source and fixing engine glitch), since 4.25 will not have any more updates and 4.26 also has the same issue:

  1. get Unreal 4.25  source, following link is a step by step instructions on how to get the source (no need for the building until  you change buggy scripts, just when you get 4.25 source unzipped from git, run Setup.bat, after that run GenerateProjectFiles.bat ): Building Unreal Engine 4 (UE4) From Source Code / GitHub - YouTube

  2. change this 2 scripts as explained in the below link, and finally, build the source 
    https://github.com/EpicGames/UnrealE...48f5a38dfb53ea

  3. compile your project from source (in the following link, instructions are around 8.50  min): Building Unreal Engine 4 (UE4) From Source Code / GitHub - YouTube

Enjoy again your UE4.25/26

Cheers,
Mike
