Unable to Launch UE 5.4

Development Getting Started & Setup
,
1

Hey guys,
I just downloaded UE 5.4 and on trying to launch a blank level I receive the error -

“Out of video memory trying to allocate a rendering resource. Make sure your video card has the minimum required memory, try lowering the resolution and/or closing other applications that are running. Exiting…”

UE 5.3 runs fine but I really want to get started in 5.4
I have an RTX 4070ti and don’t face this problem with UE. What could be causing this and has anyone else experienced it?

Coincidentally, I was installing UE 5.4 yesterday using the GitHub source code but paused the build halfway since Epic Games released UE 5.4. I deleted all the files from the Github source and uninstalled Visual Studio as well.
Could stopping that source build have anything to do with this??

Any and all help would be greatly appreciated!

I also found the same problem, updating the graphics card driver to the latest version can solve it.

Nah same issue for me, even with updating it… My other dev machine gets a different crash error related to shaders… at 45% this version, for both my dev machines has been broke… I used UE a long time and never had this happen with both my dev machines with different issues and unable to use…

Greetings @ShootingCoins1

Not having VS can cause you to run into a number of issues. But, I’m not sure if that is what is causing this problem. I’d start by ensuring all of your drivers are up to date(I know. That sounds very generic. But, it’s important!) and also consider resetting your 3D settings in your NVIDIA Control Panel back to global default.

Same issue for me. Driver update helped me

I use unreal 5.3 is Ok, but it can not work for Unreal 5.4. The best way to solve the problem is update the NVIDIA. It is work for me.

So I had this issue constantly with 5.4, and tried a multitude of suggested fixes with no luck. Eventually, I realized the solution was due to virtual texture tile size being too large (mine set to 512). Changing it to 128 solved the issue. Likely lots of different settings under Engine-Rendering-Virtual Textures you could change to optimize, but this was what fixed the perma crash for me.
