Arc B580 and X-Plane 12

[thm-unix]

Hello! I've just upgraded from GTX1660s to Arc B580 and now I'm experiencing issues with running X-Plane 12. FPS is awful (~10-15) and X-Plane crashes after a minute or so with error: "Encountered Vulkan device loss error! X-Plane cannot continue running and will now quit."

I have the latest BIOS version, Re-Bar support is enabled, kernel is the latest available (Linux 6.17.8), mesa is up-to-date (and actually even tried building the very latest dev version, still the same), vulkan-intel is also up-to-date.

I've tried removing X-Plane settings and running X-Plane from Ubuntu Live CD, but the result is the same.

Superposition (OpenGL) and GravityMark (Vulkan), though, show great results, so the problem seems to be only with X-Plane.

With the X-Plane's 'Safe Mode', it does not crash, but the FPS is still the same

I've also updated GPU firmware using igsc. This also didn't resolve the issue

Hi thm-unix,

Thank you for the detailed report about the X-Plane 12 performance and crash issues you're experiencing with your new Arc B580 on Arch Linux. I can see you've done extensive troubleshooting including BIOS updates, ReBAR enablement, kernel updates, mesa updates, and even GPU firmware updates.

The "Vulkan device loss error" combined with the severe FPS drop (10-15 FPS) while other Vulkan applications like GravityMark work fine suggests this may be an X-Plane specific compatibility issue.

To help investigate this further, I need some additional information:

1. What specific Intel Arc graphics driver version are you currently running?
2. Did X-Plane 12 work properly with your previous GTX 1660S before the Arc B580 upgrade?
3. Could you please run Intel System Support Utility for Linux and provide the report? Download: https://www.intel.com/content/www/us/en/download/18895/intel-system-support-utility-for-the-linux-operating-system.html

The fact that Safe Mode doesn't crash but still has poor performance, combined with your successful testing of other Vulkan applications, will help me analyze this X-Plane specific issue.

Hi!

1. Packages versions:

• mesa 25.2.7
• vulkan-intel 25.2.7
• linux 6.17.8
• linux-firmware-intel-20251111
• intel-gpu-tools 2.2

2. Yes, with GTX1660s X-Plane 12 ran great

3. SSU report: https://paste.debian.net/1410226/

[thm-unix]

And if that's useful, here's Log.txt from a completely clean install of XP12 that performs just the same way. 

[DeancR_Intel]

Hi thm-unix,

Thank you for providing the detailed package versions, SSU report, and X-Plane 12 log file. This information is very helpful for analyzing the issue.

I can see you're running:

• Mesa 25.2.7 with Vulkan-Intel 25.2.7
• Linux 6.17.8 with latest Intel firmware
• Confirmed that X-Plane 12 worked great with your previous GTX 1660S

The log file from your clean X-Plane 12 installation will be valuable for identifying the specific Vulkan device loss patterns.

To help complete the analysis, could you please provide:

1. What specific graphics settings are you using in X-Plane 12? (resolution, rendering options, Vulkan API settings, texture quality, etc.)

This additional information will help me correlate the log data with your specific configuration and the crash behavior you're experiencing.

Best regards,

Hi! I've attached screenshot of my GFX settings. I also tried changing them all to minimal ones. It acts the same way as when I enable 'Safe mode'. XP does not crash, but it's still ~10-15 FPS.

[thm-unix]

and the screen resolution is 1920x1080

[DeancR_Intel]

Hi thm-unix,

Thank you for providing the X-Plane 12 graphics settings screenshot and confirming your resolution is 1920x1080. I can see your current configuration, and it's very telling that even when you reduce all settings to minimal (similar to Safe Mode), you still get the same ~10-15 FPS performance without crashes.

This suggests the performance issue is more fundamental than just graphics settings optimization, which aligns with the Vulkan device loss errors you were experiencing at higher settings.

To help analyze the performance bottleneck you're experiencing, could you please provide CapFrameX data showing the 10-15 FPS performance? This frame time data will help me understand what's causing the severe performance limitation with your Arc B580 in X-Plane 12.

Additionally, would it be possible for you to replicate this issue on a Windows OS installation rather than Linux? This would help us determine if this is a Linux-specific compatibility issue or a broader Arc B580 and X-Plane 12 compatibility problem. Testing on Windows would provide valuable comparative data for our analysis.

If Windows testing isn't feasible, the CapFrameX data from your current Linux setup will still be very helpful for identifying the performance bottleneck.

Hi!

So first of all, Laminar Research released X-Plane 12.3.1 on November, 26th. It did not resolve the issue on Linux.

I installed Windows on the second drive as you suggested and tried running XP12 (I've set the same GFX settings as the ones I showed you earlier). Intel GPU drivers are the latest available. The performance seems to be kinda better (~30-35 FPS) and there are no crashes, but I expected way better performance from B580 (considering the fact that B580 is in recommended system requirements of XP12 and my GTX1660s also performed way better). CapFrameX data from Windows is in the attached files (change the file extension from *.txt to *.json and then import it to CapFrameX. Seems like JSON is not an allowed file format on this forum)

Also I tried changing the view and pointing the camera to the ground and I got 50 FPS max (this is not included in CapFrameX report), while I expected 100+ FPS (this was the frame rate GTX1660s showed in this case).

As for getting data from XP12 on Linux, I can only show you the stock FPS overlay (which also shows CPU time, GPU time, frame time etc), because CapFrameX is not available for Linux. The full screencast that shows XP12 behavior from the very start till crash is in the attached video (FPS overlay can be seen in the top left corner)

Hi thm-unix,

Thank you for the comprehensive testing with both Linux and Windows installations, and for providing the CapFrameX data from Windows along with the detailed Linux screencast. I really appreciate the thorough approach you've taken to isolate this issue.

The performance difference you're experiencing is indeed concerning. While Windows shows better performance (~30-35 FPS vs 10-15 FPS on Linux) and eliminates the Vulkan device loss crashes, the overall performance is still significantly below what you'd expect from an Arc B580, especially considering it's listed in X-Plane 12's recommended system requirements and your previous GTX 1660S performed much better.

The fact that you're only getting 50 FPS maximum when pointing the camera at the ground (compared to 100+ FPS with your GTX 1660S) clearly indicates there's a fundamental performance issue that needs further investigation beyond standard troubleshooting steps.

I need to check this further internally for additional analysis. The combination of Linux-specific crashes, cross-platform performance degradation compared to your previous GPU, and the detailed data you've provided will be valuable for my investigation.

I'll get back to you once I have more information from my review. Thank you for your patience and the excellent documentation of this issue.

Hi thm-unix,

Thank you for your continued patience as I investigate the X-Plane 12 performance issues you're experiencing with your Intel Arc B580.

I have an additional troubleshooting step I'd like you to try. Could you please test your Arc B580 with Ubuntu Linux instead of Arch Linux?

Ubuntu is the officially supported operating system for Intel graphics cards, and this may resolve the Vulkan device loss crashes and performance issues you're experiencing on Linux.

You can find more information about officially supported configurations in our documentation: Installing Client GPUs — Intel® software for general purpose GPU capabilities documentation

Since you're currently experiencing significant performance differences between your previous GTX 1660S (100+ FPS) and the Arc B580 (30-50 FPS max), along with the Vulkan device loss crashes on Arch Linux, testing with Ubuntu may help us determine if the issues are related to the specific Linux distribution or if they persist across officially supported platforms.

Please let me know the results after testing with Ubuntu Linux, and I'll continue investigating based on your findings. See link for reference: Installing Client GPUs — Intel® software for general purpose GPU capabilities documentation

Hello! Some news. LR released XP v12.3.3. It did not resolve the issue

Thanks, will be waiting for updates on the topic

[thm-unix]

Current package versions:

• mesa 25.3.1
• vulkan-intel 25.3.1
• linux 6.17.9
• linux-firmware-intel 20251125
• intel-gpu-tools 2.2

Problem is still not resolved.

[DeancR_Intel]

Hi thm-unix,

Thank you for your patience while we conducted testing regarding the issues you've been experiencing with X-Plane 12.

I have an update on our investigation. We've completed testing using both our Intel B580 GPU and a third-party RTX 4060 graphics card to replicate the issues you reported. During our testing, both GPUs exhibited the same error message and behavior that you described.

Based on these test results, where the issue occurs consistently across different GPU manufacturers and models, this indicates that the problem is likely related to the game itself rather than being GPU-specific.

I recommend contacting X-Plane support directly at Support | X-Plane, as they will be best positioned to address what appears to be a game-related issue affecting multiple graphics card configurations.

X-Plane support will have the specialized knowledge and tools to investigate this issue within their software and provide you with the appropriate resolution or workaround.

Thank you for bringing this matter to our attention, and I hope X-Plane support can quickly resolve this issue for you.

Best regards,

Hello!

I'm happy to say that XP v12.4 beta partly resolved the issue. Now I get around 40 FPS in the aircraft and ~60-70 FPS outside. Still lower than I expected, but at least it's not 10 FPS and X-Plane does not crash.

So it's great to see that some work is being done from the side of LR. Let's see how it goes further.
