Way to fix/improve global illumination?

[UnreasonablySaucyConcrete]

I noticed whenever I'm in a dark place that the global illumination acts strangely, kinda like it just splotches the area around the light source every few seconds rather than staying still. I've noticed this in another UE5 game too so I assume it's an Unreal Engine thing or Lumen thing.

In that other game it was possible to edit an engine.ini to sort of improve the GI and reduce the splotchiness, but considering Easy Anticheat is in this game I doubt I could do that. Are there any settings combinations or a Reshade shader (that doesn't need depth buffer access) that I could use to help?

Anyway to contact the devs directly and let them know about this? I've posted on Discord but no one seems to care

Gave all the game menus and the internet a quick check and found nothing. There is no way to directly contact the developers or publisher. This is more than likely an issue with Lumen than the game though, the only thing the devs could do is replace some of the GI with lightmaps in areas that have static lighting like dungeons and attempt to tweak the Engine ini themselves.

I believe this is a Lumen thing, and also that the devs are aware, because it's considerably harder to notice than it was in beta. I'm sure they'll address the areas where it's still noticeable eventually.

But they surely know more than us and have manpower to look into the problem though

Oh absolutely, I'm sure they can further reduce it, but it's just that they'll likely never fully eliminate it or get it to a point of the splotchiness and noise being unnoticeable.

Found these Engine ini options online in the Unreal Engine forum.

r.Lumen.ScreenProbeGather.DownsampleFactor=8
r.Lumen.ScreenProbeGather.TracingOctahedronResolution=16
r.Lumen.ScreenProbeGather.FullResolutionJitterWidth=0.5

The only issue... these tank my FPS similarly to Templar's settings. But in my testing they almost completely eliminate the splotching. Unfortunately they don't remove the graininess, and while it might be my eyes playing tricks on me I think these settings make the grain worse.

What gpu do you use?
I will try this, i put global illumination low and it helps, but some things gets kinda pixelated … mainly on characters outfits

I'm running a 3070ti on a mild undervolt with overclocked VRAM. I didn't really consider lowering the GI setting past medium while testing the settings I posted. I hope the settings work out well for you.

Wait i'm using 3070ti as well, might it also be the problem with our cards or driver too?

While it wouldn't be surprising with how messy GPU drivers are, I doubt it. I've seen a post from an AMD user about it on Reddit and I remember a friend of mine who played Abiotic Factor and noticed the splotching while using a 20 series RTX card.

Word of caution to whomever uses .ini commands from this topic. Some of them might break certain visual aspects of the game depending on the context. I.e. i was using those 3 lines:

r.Lumen.HardwareRayTracing.LightingMode=3
r.Lumen.Reflections.ScreenSpaceReconstruction.RoughnessScale=0.75
r.Lumen.Reflections.SmoothBias=0.25

And it seems it breaks lighting in at least cave where you open 82/83 patterns. That's why i don't really see point in blind .ini edits where you can't test things thoroughly in real time.
