Unreal Crashing after 20 seconds to a minute in a project

General Issues and Bug Reporting

Just downloaded Unreal Engine, it seems really cool, complicated but Ill get the hang of it. My computer has 8GB memory, Mac M3, so not sure if this might be the entire issue. But when I open an empty project, or even the intro tutorial project, it’s incredibly laggy. Again, might be the 8GB.

I added xcode as it asked me as well as changing something in settings that it gave me a notification about.

After I have the project open for no more than a minute, of lag, it crashes and gives me this error code the last tine i tried it:

(Not really sure what any of this says but Im sure someone more seasoned with Unreal can help, if it’s a small issue that I can fix that would be super helpful.)

Welcome to the forums.

I don’t have any experience working with mac and Unreal together but I can pretty much guarantee that it is the specs. 8gb is the minimum ram requirements but from experience I can tell you that it just isn’t enough. That’s even what the error says:

“Command Buffer Translucency Failed with OutOfMemory Error! Error Domain: MTLCommandBufferErrorDomain Code: 8 Description Insufficient Memory”

I’ll point you to this thread too as it covers some issues with xcode, but I’m fairly confident it’s the hardware limitations that are causing your issues.
