  1. Two Vulkan Issues in A27 (and unrelated choppiness caused by control groups)

    Strangely, I downloaded some games to test, and all of the Alt + Tab worked fine.

    The following is the list of games I tested.

    • SuperTuxKart (Edit config.xml in configuration folder and change "gl" to "vulkan" for the "render_driver" setting.)
    • Dota 2
    • Unturned (In Steam, enter "-force-vulkan" in the launch options under Unturned's properties.)
    • Veloren
    • War Thunder (In Steam, enter "-driver:vulkan" in the launch options under War Thunder's properties.)

    That's interesting. Probably we're doing something differently. I can try to build a modified version of the A27 pyrogenesis.exe with some fixes and send it to you if you can run and test it.

    For Vulkan fullscreen mode, after the first Alt + Tab, the animations (e.g. side-to-side moving knight and horse in the main menu) stop.
    And the mouse behavior suggests that it did switch to the browser successfully.

    After the second Alt + Tab, it's back and the position of the knight and horse has changed.
    And then, they continue moving left and right.

    That's interesting. I'd say that's a problem on the driver side since it's related only to the VGA case.

    Do you have any other game that supports Vulkan? For example, SuperTuxKart.

    With Vulkan and GPU skinning enabled, the log [(issue2)......] is actually already attached at the bottom of my first post.

    Nothing suspicious in the logs. Does the GPU skinning work with OpenGL?

    I'm not sure what you mean by "So it just stays on top?"

    I meant that it's still working, all animations are playing :)

    On 03/04/2025 at 5:17 PM, little Guest said:

    Yes. It is fine when GPU skinning is disable.

    Do you have any log after that crash? You can find a path to them here: http://gitea.wildfiregames.com/0ad/0ad/wiki/GameDataPaths.

    It seems that the main difference lies in the gui sim update.

    Ah, I see. We have some performance issues when many units are selected.

    With Vulkan in fullscreen, after pressing Alt + Tab, the screen remains stuck on the 0ad display.

    Could you try to disable borderless fullscreen by adding the following line to your user.cfg?

    borderless.fullscreen = "false"

    Hi! Thank you for the report! (And sorry for the delayed answer)

    No issue with OpenGL, nor with Vulkan in windowed mode.
    This occurs on a VGA (D-sub) monitor, but there is no issue when using HDMI to a USB video capture card connected to an old laptop.

    Is the game still playable after multiple Alt+Tab? So it just stays on top?

    On 08/03/2025 at 4:18 PM, little Guest said:

    With Vulkan and GPU skinning enabled, the screen jumps to the desktop and the program shuts down when loading the game.
    No crash report.

    Does it crash in the game or in the main menu? When GPU skinning is disable everything works fine?

    On 08/03/2025 at 4:18 PM, little Guest said:

    By the way, is it a known issue that when multiple control groups control a large number of units (e.g., 632), moving the camera—even without selecting units—feels a bit choppy?

    If profiler doesn't show performance issues then I'd expect such choppiness.

  10. Mini map showing weird colors

    The other day I was playing a game and the mini map began to show really weird colors. It would flash these colors and then show them for a few seconds at a time before switching back to normal. These color flashes occurred when there was an extremely large number of units active and fighting. 

    Could you share your userreport_hwdetect.txt?

  12. How to verify that Vulkan is being used

    What's the best way to verify that vulkan is being used as the backend? I have the option set in my config and there are no errors or warnings in the console. Is that mostly a guarantee vulkan is being used properly, or is there something in the log I could look at to verify with certainty that vulkan is being used? I did see this in mainlog:

    If your backend is set to Vulkan and no errors on start (like switching to GL) then Vulkan is working. 100% check is to look at the userreport_hwdetect file at "renderer_backend"."name".

  14. pyrogenesis.exe - Application Error

    I tried this and got the same result...

    Which OS and which version of it do you use? Maybe try to install the game to a different location (if possible)? Like another disk. Also maybe redownload the game installer or use a different source (https vs torrent).

    Dear 0 AD Team,

    I downloaded and installed Alpha 27 with utmost excitement only to get:

    The application was unable to start correctly (0xc0000005). Click OK to close the application.

    I tried the generic fixes in the web to no avail, can you help me?

    Could attach logs? (You might find a path to them here: http://gitea.wildfiregames.com/0ad/0ad/wiki/GameDataPaths)

    Currently it sounds like an incorrectly installed application. Maybe try to delete all installed 0 A.D. games and install the 0.27 version again.

  16. A27: Very poor performance on weak hardware?

    - I played a few games on debian trixie, using my old laptop with an Intel i7-4510U CPU @ 2.00GHz. I had up to 10 fps, but when it came to a 200 pop situation, it was more like 0.5 to 1 fps. I played with lowest graphic settings, which used to get me 20-40 fps on a26. I tried both OpenGL and Vulkan, no notable difference detected.
    Any idea why it is so much slower now?

    I might suggest a bit techy way: open in-game profiler with F11 on a laggy scene and share result of the appeared window.

    Hi,

    I do have an issue also, but its different from Reza. Mine, I only see parts of the units, like only a bit of the head of womens. I dont know how to do a screenshot, when I do, it's black. What is the ingame command for it ?

    I tried to switch to Vulkan, but I have an error saying the DLL cannot be find. I don't know what to do :D

    Hi! You need to disable GPU skinning in the graphics settings.

    The command for screenshots is F2 :)

    Wow. That is not a small community, granted that's not huge but that's a decent size.

    And that the only people who enabled reports, we might have noticeably more.

    Maybe @vladislavbelov will have time to update the site after the release.

    Yes, I'm waiting for the release.

    stan mentioned a few times data form the automatic feedback. Is that data somewhere available? I found this https://feedback.wildfiregames.com/ but there is only old data and nothing about daily users.

     

    There is no daily statistics, only for some period.

  24. Crash on start due to Soundmanager

    alcGetString(nullptr, ALC_DEVICE_SPECIFIER) returns nullptr or at least a char* starting with "\0" in 1.24.0

    It's only used for printing the device name into a logfile. Making the follow up code expecting non NULL segfault. Skipping that part the sound works just fine, as it's only used for printing the device name into a logfile.

    The great find!

    Hi!

    According to: 

    [E] pw.loop [loop.c:69 pw_loop_new()] 0x60457b6edb60: can't make support.system handle: No such file or directory
[ALSOFT] (EE) Failed to create PipeWire event thread loop (errno: 2)

    It seems like an OpenAL or the system problem. We can make a workaround to disable sounds for that case. Did you try any other game/software using OpenAL with the new version?
