Lumen/Raytracing

[Dusty Duster]

is it possible to disable lumen/raytracing? even putting everything on low doesn't seem to make any difference on it and it looks awful nor i want it

This game has raytracing? Have you tried setting your resolution scaling down? Found that even bringing it down to 50 from 100 gave me about an extra 20-30fps, with minimal graphics impact that i could tell

it still stays on

The dev said you can disable it by turning down global illumination, did you try that?

tried, nothing changes by changing global illumination

Searched for some solutions regarding UE5 and found this:
Go to

C:\Users\<user>\AppData\Local\AbioticFactor\Saved\Config\Windows

and open Engine.ini. Add the following to the beginning of it:

[/script/engine.renderersettings]
r.Nanite.MaxPixelsPerEdge=4
r.Lumen.ScreenProbeGather.RadianceCache.ProbeResolution=16
r.Lumen.DiffuseIndirect.Allow=0
r.Lumen.Reflections.Allow=0

I also added

r.Water.SingleLayer.Reflection=0
r.VolumetricCloud=0
r.VolumetricFog=0

there since the perfomance is abysmal in this game, sadly.

The result is night and day compared to the default settings.

wtf everyone should know about this. Went from anywhere to 30fps to 80 in a small room to 120+. Bless your soul.

I think Lumen may be baked into the game's lighting so it's always on and can't be turned off via cvar... But that doesn't mean you can't adjust all the settings lumen has to cripple it's impact on your pc performance (like lowering the values it runs with).

Good to know that my setting stuff was helpful in figuring out ways to mess with UE5 config files. Used to do this with UE4 games when those ones were bottlenecking performance as well.

Perhaps someone will know what cvar does what and can put a 'Epic' setting that doesn't cripple performance. Or even cvar that tunes lumen to be much weaker, or enables similar visuals without the performance loss.

I have a 7900 XTX and it's amazingly shocking this game manages to make it run at 25 fps when all the lighting was vanilla/default on maxed settings when it launched.

I'm more surprised in many UE5 games, they give you a toggle nanites/lumen on/off...
But no calibration for the 'scope' of how you want them to work.

These features has 'target FPS' in their code, which is 30 or 60.

If your FPS is above 30 or 60 fps, it will increase it's graphical workload until your fps becomes 30 or 60 (depending on the desired resolution, 4k for 30fps, and 1080p for 60fps).

Essentially I take a look at these fancy 'global illumination' tech and from before/after scenes, I'm like... That's barely anything noticable. Changing your monitor's gamma/contrast is going to give you that same visual difference.

The industry is basically figuring out ways to make you spend more money basically on upgrades.

Settings				Average FPS	 	PerformanceCost
Baseline, DX12 Low + Nanite 		257fps 			--
Virtual Shadows - Epic 			122fps 			-53%
Lumen GI - Epic 			129fps 			-50%
Lumen Reflections - Epic 		242fps 			-6%
View Distance - Epic 			249fps 			-3%

Looks like this developer who complains about the flaws of Epic's features is being ignored by the industry as usual. I saw his forum thread since Remnant 2's launch as Nanites was causing massive FPS loss.

Epic does not care about consumer PC performance.

Any idea what causes this weird reflection?
Lets say you wanted Lumen to work for reflections but don't want anything crazy.

Even with lumen turned off btw, I can see reflections from a distance but not when up close, as some sort of fog blocks it out.

EDIT: Resetting my graphics to vanilla, it looks like the same thing happens when reflections is set to medium or low.
Changing GI or Effects causes the reflection to look weird.

[MechWarden]

Yeah, I get that too when seeing things at that kind of an angle. Otherwise all reflective surfaces are pretty much useless as a mirror. That's literally normal for me on my old gaming rig using a GTX 1080.
