Flickering shadows/textures - seems to be an Unreal Engine issue?

[lechuck1]

im getting many flickering shadows and textures in many places, esp. around buildings/edges.. seems to be shadow related and some textures, I think its an UE issue because ive seen it in other games that use UE before they got patched.

I'm getting the same with my RTX 4080 Super, 64gb RAM, NVME SSD.

I am outside a building with tiles on some walls. The texture is flickering and showing the wall tiles, then a flicker of the mortar underneath the tiles that was used to glue them to the wall as if there is no tile there.

Its like its flickering several times a second between two different texture sets of the wall, in one version some of the tiles had fallen off the wall, in the other they are in place and the wall is undamaged.

This is at the start of the game I'm beside a building called the sphere just outside a courtyard that has a helicopter in it.

My graphics are set to epic and the game is running smooth, but I can't find what to change in the settings to stop this flickering. It is also happening on other blank concrete walls, like a flickering shadow makes the wall alternate between light and dark.

It is very annoying.

Disable Frame Generation for now. This is causing the flickering for me ...

Same problem. Disco with shadows. Nothing helps.

Thanks for the advice, but it doesn't work for me. It's annoying Nvidia put up a 'Game ready driver' specifically for this game just before it launched. That kind of implies they have looked at issues like this and ironed out any problems, but no, they haven't.

I'll join the queue waiting for a patch.

for me, disabling DLSS/DLAA worked. im using TAA/TSR for now.

Yes you are right, I switched to TAA and it worked, it's so much better. My apologies to Sharkey in the post above, I didn't understand how to disable it correctly until you explained which setting to use.

Thanks guys.

Hi all, while waiting for that patch, it costs nothing to have a proper engine.ini doing the work in line with your system configuration

Glad to hear it's a bit better for you, the below patch made a GTX 1070 able to run this game on mostly EPIC settings; :) I'm very pleased, but still want to fix it more for the horrible edges; changing to TAA :? I'm currently very pleased on FSR,
try https://www.nexusmods.com/stalker2heartofchornobyl/mods/17

but Vulkan could probably run this better than DX12 is; for the true turn of events to fix this game globally;

First of all: I am on AMD RX 7900 XT
I had flickering shadows/lights like everywhere.
Trees, electric cables, grass, walls, and so on.
I tried the shadow/lightning quality in all combinations, + upscaling method, with and without FSR 3.0... Heck I even tried it in potato quality! nothing helped

Finally found the bad boy, like 10mins ago xD
For mit it simply was:
sharpness....
as soon as I touched the slider fir sharpness it got better, the less sharpness, the less shadow flickering!
But the game looks strange without sharpness... so I have to make a little trade off...

Maybe this helps you or someone else aswell!

Had this too and found the real culprit.

Disable GSYNC (Nvidia), FreeSync (AMD) or any other kind of adaptive sync in your GPU driver settings.

With that, flickering on all DLSS, FSR, XeS is completely gone.

turning off gsync/freesync is not a real solution because playing without them is equally a bad experience.

This wasn't never fixed apparently, experiencing the same thing

it looks like it really was DLSS causing this issue. It seems using FSR 3.1 with DLSS frame gen on fixed the weird shadow issues while maintaining decent framerate (upscaling Native AA)
