FYI: Ray Reconstruction does work, but the implementation is very buggy. You have to disable and then enable the setting in the graphics menu EVERY TIME you start the game, die or reload a save.
On my setup (4070, 5800x3d, 32gb 3600mhz) it als costs about 10-15 fps. I don't think it is worth it unless you got a 4080 or 4090 and desperately want to squeeze out more visual fidelity.
There are Engine.ini tweaks that significantly improve the look of the base lumen reflection, which has much less of an impact on fps.
Hiya, I'm not well-versed in modding, so forgive me if this is a dumb question. When copy-pasting these tweaks you posted into the Engine.ini, does it matter where under [Engine.RendererSettings] it goes? Can I just stick it at the start? Or near other lighting-related things? Or should it go at the end?
Also, if my Engine.ini doesn't have the [SystemSettings] category yet, does it matter which order/where I put that?
Replacer.Lumen.DiffuseIndirect.Allow=1with r.Lumen.TranslucencyReflections.FrontLayer.Allow=1 Otherwise things like scopes on weapons will not function.
You can renable RR with the console( if You have it installed) a little bit faster then having to go to the menu each time.
r.NGX.DLSS.denoisermode 1
console does not like having a = in the arguments and will return not recognized so make sure to use r.NGX.DLSS.denoisermode 1 and not r.NGX.DLSS.denoisermode=1 in the console. that seems to only work when loading from ini.
What do you mean with scopes wont work? I tweaked my engine.ini file and my reflections in puddles etc. now look really really good. Only problem I have and I cant solve is the thing, that the reflections in my sope are extremely bad. They just look like minecraftblocks. I already tried it with the command you recommended, but the problem still persist.
Do you happen to know if there is a command for making reflections in scopes more detailed? Or is the problem probably caused by a command I use? Unfortunately, I don't know much about the subject... :D
2/16/2025 this engine tweak still works very well ESPECIALLY for flickering grass when using dlss. Thanks brother. Will test it out for a bit to make sure its stable
I have same setup as you - RTX 4070 , 5800X3D - your settings are brilliant and Im currently at SIRCAA and the reflections and clarity is SO much better. Is there a setting I can adjust to make the reflection slightly softer? Thanks for the tip
can you make a mod that DELETES reflections from the game in 100%??? i dont want them on low i want them gone. its unnecesary grafical feature thet isnt that nice at all but it drains a lot of resources and lowers performance, im completly fine with blank water or window i dont need reflections at all
Options for you. As it's an unreal engine 5 game, it's very easy to alter them.

r.ReflectionMethod=0 or 2 1 lumen, 2 is screenspace

Also use [ConsoleVariables] instead of anything else at the top in engine.ini, for any custom console commands, no need to make it read only, if some command gets deleted, then that wasn't recognized by the engine anyway.

copy and paste these lines into your Engine.ini no matter where.

its hud is bugged and currently need to do this every launch or death.
Don't see this in any of the options for graphics/display.
