In 11.50b6 we added a command line argument to run Aftermath, a debugging utility, hoping it will give us more insight into device loss errors.
A “device loss” error is specifically the crash that accompanies the on-screen (or log.txt) error message “Encountered Vulkan device loss error!” Using Aftermath will not help us investigate VRAM issues–that is a different issue entirely.
If you are on Windows, have an NVidia GPU and you see a device loss error followed by a crash, you can help us track these bugs down by running X-Plane with Aftermath enabled. We know from 11.50b5 that many devices are not compatible with Aftermath, so if you crash and burn immediately, you can go back to using beta 6 without the extra command line option.
We will be using the command line via Command Prompt. (Here are instructions on getting started with this if needed.)
Launch X-Plane from the command line with the following flag:
You can then try to reproduce the steps that caused the initial device loss, or just fly as usual. If device loss happens again, the auto crash report form should come up again. Please fill out your email and submit the auto report to us for investigation.
