Still crashes for me with 4.24.1 and latest Studio drivers. ---

■■■■, I’ll do more tests, but I’ve ran 4.24.1 for about half an hour without a secondary screen without a crash. On the bug page here: [Unreal Engine Issues and Bug Tracker (UE-72117)](https://issues.unrealengine.com/issue/UE-72117) the issue is planned to be resolved for 4.24.2 EDIT: Target fix is now for 4.24.3 ---

Thanks for that. Yes, the Epic Staff did mention that this issue is very much related to driver updates. Hopefully, this kind of complications involving a laptop with an Intel integrated GPU and a NVidia RTX card will be solidly fixed, won’t reappear nor suffer from any kind of regression again. Cheers, Stef ---

Anybody know if this has been fixed in 4.24.3? ---

Hey Graeme, On the [issue’s page](https://issues.unrealengine.com/issue/UE-72117), the ‘target fix’ has been updated to 4.25 - that said I couldn’t reproduce bug with 4.24.2 and I haven’t tried to reproduce it with 4.24.3, yet. ---

This is happening again. I have an i7-9750h with an RTX 2060 mobile (laptop) version, and every time I restart the editor after enabling DirectX 12, Skin Cache and Ray Tracing, it crashes. Looks like the issue isn’t fixed after all. [Previous page](https://forums.unrealengine.com/t/ue4-freezes-when-ran-with-dx12-arg-on-laptop-running-2080-maxq-without-secondary-screen/443797.md?page=3)
