Some players are reporting problems with our Unreal Engine 4.15.1 game crashing on launch. After analysing various crash dumps from the affected players, it looks like the crash is coming from FD3D11DynamicRHI::SetupAfterDeviceCreation(void):
Glad I am not the only one who noticed this issue. Hopefully this can now get resolved soon now that it is proven that the issue is on the engine side.
I noticed that your tracked bug report notes that this happened on AMD Radeon HD 6250 Graphics. The logs that I have received before I had to revert to 4.14 were from the following models: AMD Mobility Radeon HD 5000 Series, AMD Radeon HD 6450, AMD Radeon HD 7620G, AMD Radeon ™ R7 370 Series
That is a pretty big range so the issue might be related to software (drivers) instead of hardware (AMD) since I noticed that all my reports were on drivers from 2015 but that is just a guess really. Either way this should be fixed regardless since it is a regression from 4.14. Maybe sharing your full logs might help uncover more information.
I still have folks reporting this type of crash. Did you get anywhere with this? I think you are correct that it is related to AMD cards, I haven’t had anyone with a Nvidia card report this issue, though I am finding it hard to nail down the model ranges.
I’ve reached out to some users but still haven’t gotten a project that reproduces this issue. If you happen to have this issue please upload a sample project that breaks after updating to 4.15. This will be very helpful since we are having issues reproducing this bug.
Also, please leave your DxDiag as well since this issue seems hardware specific.
Feel free to leave a comment with this information and the post will reopen!
If you could get in touch with a user and see if they can reproduce the crash with a small sample project that would be best. I understand that it may be hard to lock down the issue if you can’t reproduce it on your end. If possible try to limit the amount of content you send.
its not just your game many other games had the same crash for me all from ARK:survival and some others then my F-secure registred an virus called: insulam-win32-shipping.exe and now all games works fine
I would suggest compat testing with AMD drivers from 2015 or earlier as this seems to be how the majority of crashes have been reported.
If it turns out it is only related to older drivers please consider fixing it anyway since this is a regression from 4.14.3 and lots of people run on older drivers and will simply return the game and/or down-rate it if crashes when started for the first time.
This is unfortunately still an issue with Unreal Engine 4.16.0. I have upped my game’s minimum system requirements on the Steam page in order to cut out the mostly (now legacy) AMD cards that this crash is happening with, however I still get a spattering of negative reviews complaining that my game crashes on launch.
I will provide more information when I can, though splitting my time between development and guiding users to submit dxdiag reports is difficult.
