I recently been having a problem with my unreal engine randomly freezing, it mostly happens when I go to the settings in unreal and then the screen just freezes. This is a new PC so I don’t know if it’s a problem with the PC or maybe something else. Also I tried running games on it and games that are run by unreal engine also freeze. Is there a way to fix this.
Thanks
Hey there @Santi_852! Welcome to the community! May we know your computer’s specs?
Hello yes, I have a ryzen 6 7800x3d, amd Radeon RX 9070, and a ROG strix B650-A gaming WiFi motherboard
it is a rysen 7 not 6 that is a typo
Looks like your specs are more than fine, it’s possibly a configuration issue. I know you mentioned the device is new, but let’s start with general troubleshooting (which will be a bit redundant).
Does the crash context appear or does it just freeze graphically?
Some possible graphical workarounds or fixes: (though the original post geared for Nvidia GPUs should still be somewhat relevant)
It just freezes graphically.
I did most of the recommended steps and it still freezes
That’s unfortunate! One of the primary difficulties with figuring out freezes like this is that if the engine doesn’t actually crash, the logs may not even generate at all, much less provide useful actionable information.
Do you have Visual Studio installed and setup for C++ already?
If so, let’s see if we can get any info out of the engine itself. Try appending -d3ddebug to the launch arguments for the engine exe. Open Visual Studio, Go to Debug > Attach to Process..., launch Unreal Engine using the exe with the appended debug command, then switch back to Visual Studio. You should see UnrealEditor.exe appear in the list of available processes. Select it and click Attach.
Now, look at the Output window in Visual Studio (if it’s not open, you can open it via View > Output ). You can then copy that and sent it here between the code syntax backets like this:
` ` ` Your log ` ` `
Just remove the spaces between the “`” characters. (Not sure if the forums have an escape character for this).
Random freezes since 5.5 for me on 4070.
I got a solution, somewhat. so basically I was trying to stress test the PC by playing games and realized that all the games were using the integrated gpu, so i went over to disable the integrated gpu and now unreal does no freeze. however, it is very laggy like the frames dropped to 2 frames a second which wasnt happening before. is there a way to fix this. i am using a AMD gpu if you are wondering
update i found out why the fps is so low, the gpu is not even working when i opened task manager the cpu was a 99% and the gpu as at 1%. was that the problem and if so is there a solution
It sounds like your GPU isn’t being used by windows or the engine itself. Do you have an integrated GPU that it might be trying to use?
One common issue is windows forcing the wrong GPU to be used, you can remedy this by going to windows Graphics Settings and making an entry for the editor and in the options choose your correct GPU:
If that’s not the case you may need to check your Adrenalin settings.
i just changed the setting but it still freezes, is there another setting i might need to change.
The Windows GPU assignment should work barring any other software between for example the drivers and configuration. I believe there used to be another setting inside of AMD Adrenalin, however I don’t have an AMD GPU on hand to verify the most recent options.
For anyone wondering, I found the solution. Since it was my first PC build, I made a common beginner mistake—I had plugged the HDMI cable into the motherboard instead of the GPU. Once I corrected that, everything started running smoothly.
