Help! Crash on opening of project, not enough Vram

[Jay-H]

Hi,

After upgrading to 5.5.1 from 5.5, Unreal is crashing at the start on a specific project. I’m getting an out of VRAM error.

Unreal crashes after I close the error. On loading, the Task Manager shows I’ve plenty of VRAM (3.8/8GB), what’s going on?

I’ve done a clean install of my Nvidia drivers, tried the Studio and the Game Ready Drivers. I also did a clean install of the HUB and Unreal Engine 5.5.1.

Any one know what’s going on?

Currently I don’t have access to the project now as it crashes on loading, what should I do? Is this a bug?

Thanks.

Try this

"c:\Program Files\Epic Games\UE_5.5\Engine\Binaries\Win64\UnrealEditor.exe" d:\MyProject.uproject -ExecCmds="scalability 1"

At least you can get the file open that way.

Thanks for the tip.

I changed the path to suit my filenames, but it just kept opening up the default UE Starting Panel (after the HUD) and didn’t go further to load the actual project.

Instead to load the project I edited the “Config/DefaultEngine.ini” in the project folder and changed the map (listed twice) to be blank. This allowed me to load the project without issue - the project opened with no map selected, allowing my to load one manually.

I was then able to run the project with the detailed map that crashed with the Vram error totally fine. Although that said, Once the game was running I did notice my Vram was nearly maxed out (7.2GB of the 8GB)

I’ll have to see how I can optimise more, as this wasn’t that large of a map really. Unreal is very hungry on Vram!

I still don’t know if it is a bug or not. Surely you would think that the project should load, but then just not run well, and not just open and crash straight after the error seems a little odd.

Still learning.

It was supposed to be on one line btw

It’s probably textures using all your VRAM.

Right click on the level in the content browser and choose ‘size map’ to see what’s going on…
