Any suggestions to fix this visual glitch on models?

I’ve noticed this happen on Unreal Engine games and just thought it was something funky with those specific games (such as Fortnite) but pretty sure it’s just the engine at this point. Any ideas as to what’s causing this?

This is a brand new project on 5.3 where I loaded it and just hit play.

i have never seen that happen before.
are your drivers ok?
try packaging your game and put it in another pc (or publish here) and see if it reproduces.

This happens on my computer with most, if not all, unreal games and character models. Any other engine, or game made with an engine other than Unreal, this doesn’t happen. I can install Fortnite and achieve the same effect.

What I’m trying to diagnose here is how I can fix it on my specific computer.

Updating and downgrading drivers has no effect.

Processor AMD Ryzen 9 5900X 12-Core Processor, 3701 Mhz, 12 Core(s), 24 Logical Processor(s)

if it happens with fortnite and other ue games it’s highly likely something in your configuration, not something on the project. maybe a bug in ue’s engine.
though to me it looks like some memory is not being transferred or som ememory corruption is happening. maybe at a gpu level. maybe some specific ue optimization.
have you tried playing with ue graphic scalability settings (low, mid, high, epic, cinematic) and see if some of that makes a difference?

also what version of windows are you using?
funny because we have a similar rig and i’ve never experienced something like that.
mine is
nvidia rtx 3060ti driver 527.56 (now i realize its outdated)
ryzen9 5950x 16 core
win 11 and linux kubuntu 22 lts

try downloading a linux livecd and run a memcheck (there are some very small disks out there)

Hello, I have exactly the same visual glitch. It happens to me in all the games with unreal just like you. Have you been able to solve it? If so, you can guide me to fix this annoying error. Thank you!

I have not. Thought I was only person on the planet that had the issue. Just met someone else with it in Nightingale.

So, it turns out it’s some sort of thread desync between AMD processors and Unreal Engine. The fix is to disable cores (in pairs) until the issue goes away and then either keep those cores off for the application / game or create a profile to set it that way when you launch it. https://www.reddit.com/r/AMDHelp/s/msjBxSTj2y
