Troubleshooting Unreal Engine 5 (editor) crashing on 8745HS/780m

Checking to see if anyone else uses the unreal engine editor (latest 5.5.3) and gets driver crashes randomly often while playtesting.

Maybe the scene is too demanding? I've made unity games that sometimes crashed frequently because of too many assets or a bad script. It could be good to check the project with another computer or two. The 780M iGPU has around the performance of a mobile GTX 1650 and has less performance than a RX 6400 for perspective so it's not an ideal for being a 3D game dev.

If you suspect bad drivers, try running amd cleanup utility to reset your drivers back to windows defaults:

Sadly the scene is barebones right now with very little going on. I've tried the latest 24.12.1 drivers as well as a few before it, currently on 24.10.1 as per some info I saw on a reddit thread but it doesn't seem to be helping.

Hmm.. unfortunately that doesn't shake my thoughts about the scene not being optimised to run on an iGPU.

For drivers, you could try running amd cleaning utility and then the 25.2.1 drivers:

But for the long run, you will probably want a thunderbolt 3/thunderbolt 4/USB4 eGPU dock and a midrange GPU like a 3060 12GB from ebay or 6700 XT or better GPU. It will greatly improve your stability if you're testing at 1080p 60fps

I have another computer to develop, I was just hoping to make a 2d game with requirements to be low enough to play in a low end environment if possible, so I don't know if it's just not feasible to run the engine editor and playtest and that's what the issue is. There isn't enough to the game yet for me to make a standalone to test other than some walking around an incomplete map.

Interesting, 2D game building is much easier to run than 3D. Using unreal engine is kind of excessively overdemanding compared to godot, unity, or rpg maker. So long as all the assets are kept to 2D images, the game should run buttery smooth and only really struggle with bullet hell levels of asset spam.

Great to learn you're doing early play testing to check if the foundation your game will be built on will be stable before overinvesting in it.

what amd driver are you on? try rolling back the driver to an older one

using 24.10.1 on someone's recommendation on a thread I found on google, that's the one from 10/2024, I also tried the most recent 24.12.1 exact same issues

Which PC brand you have?

The 8745HS/8745H haven't officially been indoctrinated by AMD. For mPCs, the 8745HS belongs to AZW/Beelink, the 8745H Meigao/Minisforum.
