Hello, i have a big problem, been working on a project for over 10 month now, and it’s releasing on steam but people report a crash somewhere, and after investigation i can reproduce the crash even in my viewport.
It’s always the same, i go somewhere, there is nothing in particular but i crash. Message is always the same
DashOrDie.log (212.6 KB)
So i attached my log, maybe someone have an explanation for this ?
It’s very frustrating, i can’t get any information of WHAT have crashed…
thanks much
If you download the debugger symbols, you’ll get a much better idea of what’s going on

Hello, thanks, i’m not coding in C++ … is it really usefull ?
Yes, instead of giving you a helicopter view, it actually tells you the chain of events that caused the crash.

You were right, i have more information now, but i still can’t figure out what the problem is !, here is what it gives me:

Well, your GPU is crashing.
Things to check out
Do you have the latest drivers ( studio, not game ready )
Is your card up to the task ( 1660 or above with >= 6-8GB VRAM )
Does it happen in any level, or only one with a lot of assets?
You might need to go back to DX11? ( that really depends )

I’ll try what you say, i have an EVGA 3090 with game ready drivers so i’ll swap.
It happen in a specific level, when i look in a particular direction but it’s so vague, sometimes it doesn’t happen but it happen 80% of the time at the same location, i already tried to remove stuff but i can’t find out what it is, it’s VERY difficult to reproduce the crash as sometimes i just wander in the level waiting for it to happen…

Ok, so 2 is out.
Also 4, if you have win11?

Like I say, you can probably stick with DX12.
I’m only guessing from the log, but I’d say, it’s crashing while allocating memory for rendering. That might mean your GPU is running out of VRAM?
Have you tried switching between forward shading and deferred?
When you’re running in the editor, do you get any warnings or errors in the log?

Ok,
However my game looks very ugly…
There is a few warning in the output log but nothing really problematic, just missing objects or this
and this while playing

Well, some pattern is emerging
I saw this
are you using that console command somewhere. Maybe try disabling that first, see if it makes any difference.
And, strangely, switching back to deferred rendering might be ok now? ( possibly )
Looking at it a bit more, I see of course
I think that’s too much of a coincidence. You’re getting an RHI crash, and something isn’t right here.
There’s an article here about PSO
I’d have a go at turning it off. Did you turn it on specifically?

Hello afer hours of search, it was the loca height fog that was make me crashing, removing it solved the problem… i don’t have any other information !
Thanks for your help, it’s still weird

Well spotted!
What gave you the idea is was local fog?
I have messed with local fog quite a lot, but at the moment, I still find fog cards look crisper. The local fog is fairly messy
I don’t know if you’ve seen this
Bit of a mare to write and understand, but I think he gives the material away. Looks much better in my opinion ( but might be heavy, not sure about that ).
