I am working on a project now for about 150 hours, everything is running fine on my machines and I tried it on different computers of friends with different GPUs.
First everything seemed to be fine.
It ran successfully on computers with the following GPUs:
AMD R9 290, AMD R9 290X, Nvidia RTX 3090, Nvidia RTX 3080, Intel Integrated Graphics, AMD RX 6900XT
Off course therefore I first thought everything is fine.
But then a friend tried it on a PC with an RTX 2080 Ti and another friend has an RTX 3070 and there it is crashing directly after executing the .exe file.
They just get the following error:
Fatal error! Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x00007ffd73d30918 0x00007ffd7317aef0 UnknownFunction ] 0x0000000000000019 UnknownFunction ] 0x000001cab0004f70 UnknownFunction ] 0x0000000000000030 UnknownFunction ] Crash in runnable thread TaskGraphThreadNP 0
Of course, I cannot debug it directly because everything is running fine on my systems. But it is a big problem if it is not running on 20% of all PCs.
Any ideas what I could do to find out the reason why it is crashing on certain PCs?
I have no idea if it is the hardware or the software environment but every ,normal" game seems to run fine on these PCs.
The only thing I am doing with C++ is this: https://forums.unrealengine.com/deve…212#post588212
But why should it not run on some PCs?
I’ve now sent these friends clean UE projects to check if they can run Unreal Engine 4 Projects at all.
One similarity of all crashing PCs is that they have Steam VR installed and I think they use a insider build of windows, but no VR headset is plugged in.
