When we released X-Plane 11.51 beta 2 last week, we included up-to-date Aftermath support. Aftermath is an NVidia driver feature that catches detailed information when the GPU crashes (e.g. “device loss” crashes).
Full Aftermath debugging slows X-Plane down. The sim is still flyable, but you might go from 50 to 35 fps, for example. It’s noticeable, so we didn’t just turn Aftermath on for all eligible users. It’s too big of a perf hit to just leave it on all the time.
Unfortunately, while we know from auto-crash reporting that device loss errors are happening, we also know that no one is using Aftermath to capture detailed information that we could use to find and fix the potential problems in X-Plane.
So: if you hit device loss errors while flying with Vulkan on Windows with an NVidia card, please follow these instructions and run with Aftermath for a little bit. If you can drop us a few auto-crash-reports with Aftermath enabled, it could get us the key breakthrough we need to fix device losses.
Beta 3 Stuff
X-Plane 11.51 Beta 3 is here – here are the release notes. The most notable change is that we now have the new Gateway airports!
Tyler also fixed some low level networking bugs. This doesn’t change how multiplayer fundamentally works – if you can’t do a LAN flight across your WAN or you need command line magic to get the right NIC, that’s all still true and really not in the scope of what we’re fixing in 11.51. This whole beta run is targeted bug fixes.
