Im having constant crashes in Windrose, usually already in the menu or shortly after loading further | Windrose | Page 1

Important context:
I was able to play the game normally before.
These crashes only started after the hotfix on April 16.

I also already:

deleted the old Saved folder completely
went through all official troubleshooting steps
after that, I also tried to troubleshoot the problem further together with ChatGPT, including additional log analysis and custom config changes

My system:

GPU: RTX 2070 8 GB
OS: Windows 11 25H2
Driver tested: NVIDIA 595.71 (I also tested a newer driver before)
Game version: current build from April 16, 2026

What happens:
The game crashes in the menu or shortly after progressing further. In earlier logs, I got this fatal error:

Transient allocator failed to allocate Buffer Lumen.RadianceCache.PriorityHistogram

From the logs, it looks like the crash is happening in the UE5 D3D12 renderer, likely related to Lumen / Virtual Shadows / DX12 / VRAM allocation.

What I already tried:

verified game files in Steam
restarted PC and Steam
deleted/reset local config files
deleted the old Saved folder completely
deleted shader caches
used launch options: -windowed -ResX=1280 -ResY=720
rolled back NVIDIA driver to 595.71
created custom .ini files to disable / lower:
Lumen
reflections
virtual shadows
volumetric fog
other scalability settings
followed the official troubleshooting steps first
after that, I also did further troubleshooting with ChatGPT, including reviewing logs and trying additional config-based workarounds

Important detail:
Even after creating custom config files, the logs still show settings like:

r.ReflectionMethod:1
r.DynamicGlobalIlluminationMethod:1
r.Shadow.Virtual.Enable:1
r.Lumen.DiffuseIndirect.Allow:1

So it seems like the game may be overwriting or ignoring local renderer overrides.

Summary:
At this point it looks like a game-side UE5 / DX12 rendering bug rather than a corrupted install or save issue, especially since the problem only started after the April 16 hotfix.

Logs are attached.

And how do you play? (I know it might sounds irrelevant but it may be not) Do you host a server or play solo/offline?

I bought a Server a Gportal. Friends are playing on it right now. But the crash happens alls the time. It doesnt depends obn the mode. Interesting.. if I stay like 5 minutes ins thee menu and do noting. Suddenly the game still crarshes and Im back to Win11

#

So its relevatet to some grapic driver issueues

#

nothing to do with the server connec

#

Before the Hotfix on 16.4 everthing was fine. So it has something to do with the hotfix

replying here to monitor - we're having the same issues on our g-portal server

iron idol Apr 17, 2026, 6:56 PM

#

This one is not connected to G portal

#

Don't hijack other threads please, thankls

So from the looks of it we can deduct two things

RAM is your main limiting factor. If it's possible - try rebooting and then launching only game and see if issue remains.
You have a lot of crashes on... a lot of different things. It looks like your RAM may be failing. I would suggest to do any RAM test and see if it's alright

Thank you for the answer.

#

I did the RAM failure Test. Everything is fine. I closed every unnecessary Task in the Backround. When Windrose is runnig the RAM is at ~54%. The crash still happened in the loading Screen. Here is the Log from the latest crash.

Let me take the logs

#

@turbid tulip Any change you have crash dumps? they should be located in one of two places

#

%localappdata%\Local\R5\Saved\Crashes
%localappdata%\Local\R5.sentry-native

Hey, finally I found a fix for me:
I created an new local Windows User Profile. Under the new profile the crashes doesnt happen anymore 🙏🏻
