So Unreal is crashing every 10 minutes or so, most commonly after PIE(play in editor) for my VR game. The crash makes no sense as I absolutely have plenty of Video Memory.
No other major programs are running in the background and the GPU has plenty of memory left when the crash occurs.
As you can see, Unreal is using just above 2048Mb of ( assuming video memory ) which would correlate well to taskmanager’s numbers of current usage.
I see no indication that Unreal is actually out of video memory, and I see no reason Unreal should think that it is. So why this is happening is beyond me at this point.
Here is a screenshot from Task Manager, here you can also see its not nearly hitting the limit.
Have you verified your installation of UE and checked your Nvidia settings? You may need to do a reset on your global settings if there is a possibility UE is trying to use built in graphics instead of your graphics card.
In the meantime, check out this thread that may have a possible solution to the problem you are currently facing:
Thanks for the quick response!
It is putting load on the GPU so I don’t think Unreal is trying to use build in graphics.
However, following the post you said, I increased the Pagefile size, this solved the issue.
So it seems to me Unreal is falsly reporting “Out of video memory” when in reality it’s maxed out the pagefile size.
This error message should be changed to reflect what is actually wrong, instead of sending people on a merry chase thinking something else is causing the issue than what is actually causing the issue.
I recently have samiliar issue, mine is 13900k + 4090, seems to be a bad combination some how. But I kinda found a work around, goto Intel website and download “Extreme Tuning Ulitily”, then set p-core and e-core down a little bit, and the crashes and blue screens never showed again. Worked for me. Just give it a try.
