I have a good PC my cpu and gpu usage dont go highert than 60%.
It is soooooooo laggy its crazy.
it uses like 15 gb of ram (it does not top it off) and about 12 Vram (i have 16)
Its not a hardware issue at all. it doesnt matter what settings i use. i freshly installed the game few days ago wantet to get back to it, and it is awesome, but damn. it is tough to play. pretty much unplayable.

Have you tried if it’s the same when you remove the mods from the mod folders?

@AR_TALK

Remove Downloaded Mod Files

Some mods can conflict with game execution, leading to crashes.

If you have downloaded any mods, please back up the mod files and then delete them before launching the game again.

Mod File Paths:

• [Windows] Documents\inZOI\Mods\88849
• [Windows] C:\Program Files(x86)\Steam\steamapps\common\inZOI\BlueClient\Content\Paks\~mods
  And you could try to verify your game files on steam. A guide is here:

How to verify your game viles via steam

Verifying your game files via steam has already helped many desparate players and solved lots of various issues with the game, yet still it isn’t listed in the ‘Resolving Crash Issues’ guide. So here’s how to do it open steam open your steam Library rightclick on inZOI (as shown in the first pic below) select ‘Properties’ ‘Installed Files’ should already be preselected, if not, select (see second pic below) select ‘Verify integrety of game files’ (see second pic below) [grafik] …

I just tried it. I deleted the folders and verified game files. nothing changed.
this is the same problem i had when the game launched. i bought it on the release week. and quit it after about a week or so because of this exact thing. and its still here.

It’d be very helpful to see screenshots of your game’s settings.

Please also feel free to read through this compact issues guide I posted recently. Some of the listed configurations might help: inZOI – Graphics & Performance Guide (What Actually Matters)
→ I’ve done some research on your GPU and noticed continous issues in combination with Raytracing. You can take a look on how to tune it down in the thread mentioned too.

[Jewelz]

as i said, i tried all presets and turned off ray tracing. Its not a graphics problem.

It stutters in a Rhythm every 1/1.5 seconds. i have no performance problems in other games

Ah okay, I see. Would you kindly share a dxdiag of your current system with us?

If you haven’t done this before, here’s the part of an official guide that describes how to:

Oh and i just want to add one thing. its not an issue for me because i dont use it but, every time i turn on frame gen it works even worse and crashes after 5 minutes or so.

Thank you for the dxdiag

Based on it, the hardware itself is more than capable. No obvious “too weak” component. A few things stand out that could explain the rhythmic ~1–1.5 second stutters and the Frame Generation crashes:

Windows 11 Build 26200 (->Preview/Insider branch)
The system is running Windows 11 Build 26200, which appears to be a Dev/Canary/Preview build rather than a “stable release”. Certain games, rendering paths, or Frame Gen implementations can behave unpredictably on preview builds. It would be useful to verify whether the issue also occurs on a stable Windows release channel.

Very high page file usage + low free space on C:
DxDiag reports approximately 40 GB of page file usage, while drive C: only has around 25 GB free. Even if RAM/VRAM are not fully saturated in monitoring tools, heavy paging activity can cause regular, rhythmic stutters like the ones described.
As a test, I would recommend freeing up significantly more space on C: (ideally 60–100 GB free) or moving / adjusting the page file to ensure it has sufficient headroom.

Multi-monitor setup + HDR + mixed refresh rates
The system is running two active displays (extended mode), with HDR enabled. One display is at 2560×1440 @ 240 Hz, the other at 144 Hz.
Windows + HDR + mixed refresh rates + VRR / FreeSync can sometimes introduce periodic micro-stutter, especially depending on whether the game runs in borderless or exclusive fullscreen.

Quick tests that may help isolate if that’s the issue:

• Disable HDR in Windows (both monitors)
• Temporarily disable the second monitor
• Match refresh rates (e.g., both at 120/144 Hz)
• Compare borderless vs exclusive fullscreen

Frame Generation worsening the issue + crashing
Since enabling Frame Generation makes the stutter worse and eventually causes a crash, this strongly points towards a driver-level or overlay-related interaction.

I really hope this helps. Please report back to let uns know how further testing worked
