INTERMITTENT CRASHES IN VR:

• Crashes reporting a problem with the OpenXR runtime, or other intermittent crashes: The majority of these issues have resolved, but please see our FAQ entry here which has solved the issue for the majority of user-defined setting adjustments these cases: https://cyan.com/docs/firmament-crashes-with-this-message-failed-to-wait-on-acquired-swapchain-image-this-usually-indicates-a-problem-with-the-openxr-runtime-how-do-i-fix-this/
  
  
• Crashes using Vive HMDs: If you are experiencing crashes while playing Firmament with a Vive HMD, please enable the “ViveVR OpenXR SRWorks” option through SteamVR, as this appears to prevent various crashes from occurring through OpenXR (unfortunately not something we can resolve).

CRASHING ON STARTUP: If you’re on a windows machine, specific CPUs have a hardware issue that cause a crash on startup or between loads. You can find more information on it here, in addition to workarounds: https://cyan.com/docs/firmament-crashes-during-play-or-closes-before-the-menu-sometimes-shows-an-error-message/

“RAD has become aware of a problem that can cause Oodle Data decompression failures, or crashes in games built with Unreal. We believe that this is a hardware problem which affects primarily Intel 13900K and 14900K processors, less likely 13700, 14700 and other related processors as well. Only a small fraction of those processors will exhibit this behavior. The problem seems to be caused by a combination of BIOS settings and the high clock rates and power usage of these processors, leading to system instability and unpredictable behavior under heavy load.”

Unfortunately, this isn’t anything Cyan can fix on our end. You may have even encountered this in other games made with Unreal Engine 5. It’s about how your CPU interacts with software a part of Unreal, and as noted in links in the FAQ, Epic Games is aware of the issue and can only suggest the workarounds as the solve for this at this time.

If you are unsatisfied with the workarounds, please reach out to your hardware manufacturer and Epic Games.

APP HANGS ON STARTUP: If you are experiencing a crash or hang on startup outside of the scenario described above, and if you have a customized or older VR setup with options you can't recall whether or not you've turned on or off, please disable the "motion compensation layer" in your OpenXR backend settings. Yes, this applies to the game running in 2D mode as well. This appears to be an engine bug prevalent in our version of Unreal.

(Mac Only): We require MacOS 14.5 to play Firmament . If you are on a MacOS version lower than 14.5, the game will not run and may crash on startup with an OS-level message. These requirements are listed in the system requirements on our store page.
