Here’s another video of the problem and I do have frame gen turned off, so that didn’t solve the issue for me. I have this problem both in Dowon and Blissbay.
Improtant to note: I didn’t have it before the december update, but since the december update it’s really bad. To help with your investigation I have included my graphics settings in the video.
I’m on an RTX 5070ti with the latest Nvidia driver (591.59). I reverted back to an older driver but that didn’t solve the issue unfortunately.
@NovelistAnne hmmm if i remember correctly, I also deleted all these files that is in the windows folder which is located in your appdata. idk if it will do something but thats what I also did.
Tried this, no change unfortunately. I’m annoyed because I never had this bug lol and now since the update I suddenly do.
Yes the flickering lighting is very annoying, I’ve seen this in multiple houses and neighborhoods, some of them come off items like the gaming pc, others are just in the middle of trees or whatever is in the neighborhood.
It will not be the first game I can play on ultra and put everything on min, nice find 
It started to me yesterday. Same game, no options changed.
What I did yesterday? Upgrade to the latest version of my NVIDIA Drivers (for my 4070Ti).
So I just reverted to previous version of it by going into control panel, display adapter, properties, drivers and there’s an option to return to the previous version.
Booted the game up again, and the flickering is gone for me. Now back to playing
But boo-hoo, no new GPU drivers for me.
I’m glad you can use the previous driver without flickering . I have an NVIDIA RTX 4060ti installed in my PC and it flickers regardless of whether I use older drivers or the current driver. I have also changed the settings several times. This flickering does not affect all lights, so I only use the integrated ceiling lights to avoid flickering in the building. I hope that this problem will be fixed one day.
There was also massive flickering in Kjun’s video from yesterday -.-
Outside in bright daylight 
They should be aware of it so I hope there will be a fix for this soon
Is there a status update on this? Any perspective on a fix coming up soon? I really want my realistic shadows on because of how badly yellow my game is without them, but the flickering is sooo annoying.

Thanks for sharing! Since this is the same issue with The lights are flickering throughout the house, I’ve merged your post into the existing under_investigation thread to keep all related information in one place 
same here, did it work with you?
DLSS 4.5 update & Perfermance Mode = no flickering
I don’t want to run in performance mode though because it makes the game super grainy. It should work properly on the highest settings. DLAA is the only setting that somewhat reduces the graininess. But the shadows still flicker there with DLAA + frame gen x2 + realistic shadows on.
Haven’t seen any update on whether this is being fixed in months now… is more info needed? What’s the status of this?
From the numerous tests I ran on my own setup with the game, I assume (like in many current games) the issue causing the flickering is closely related to the AI-based graphic systems. Unfortunately, there’s no mention for a bug fix yet. It’s already part of the known issues list:
Yeah, I’m not just experiencing it in Cahaya though but in Blissbay and Dowon as well.
Yes, I agree. This bug occurs in all three cities, so the known issues list should include all of them.
I hope they fix this quickly, I cannot update my GPU drivers, if I do InZOI flickers everywhere for me as well.
That kind of bug should get priority IMHO. It’s just bad publicity.
Hello everyone (@here),
Could you check if this is still happening after updating the engine to 5.6 version?
