  3. Vulkan - new graphics API

    Anyway, I opened the atlas and found it to still use gl.

    Vulkan is disabled in Atlas, as wxWidgets doesn't provide loader for that by default.

    There I played with various textures and nubia dirt 1 2 3 but not 4 all show the same shadowing behavior, it's just a lot less obvious with gl than with vulkan. Ie less dark and can barely pass as just wet.

    Then it seems the known problem of broken materials.

    two new errors, the texture decode issue possibly not related to vulkan specifically:

    Updated.

    There are some shadow like artifacts (map nubian frontier)

    Could you run the game with validation enabled?

    Isn't there a bether solution than asking the users to report all missing shaders? Surely it will not be tested exhaustively and some shader will be missing in the release.

    It'll cost too much my time now or too much space for shaders. So I chose a compromise, I believe there're not so many shaders left and I have a validation script to fill possible holes.

    Switching from fullscreen to windowed stretches the view horizontally possibly by gui.scale

    Only view or window as well?

    Game starts successfully with Vulkan renderer

    Did you experience any performance difference?

    @vladislavbelov there is also new ticket https://trac.wildfiregames.com/ticket/6681

    Yeah, I'm aware of it. It needs some investigation as we can't distinguish that SDL error from a regular one.

    Vulkan - new graphics API

    in Game Development & Technical Discussion

    I was doing different refactorings of our engine for last 1.5 years. It's allowed me to add a new backend (graphics API) - Vulkan. It's relatively new API (as D3D12) which allows us to have a more predictable and stable performance. And in some cases even better performance. But not always as we use it in a single thread yet.

    Vulkan drivers from different vendors are usually much lighter than GL ones. That's the way to have less driver bugs and crashes. But we still need testing how it works on different hardware. So everyone who has a Vulkan compatible device please try to enable it in options (along with feedback). If you're able to run SVN then you already can test it. Else wait for the next RC. Note: to run the game you'd need to download and install a separate mod with precompiled shaders (it'll be bundled in RCs and the Release): https://releases.wildfiregames.com/rc/0ad-spirv.zip. Vulkan can't run pure GLSL shaders (which we use for GL), it uses a special binary format for shaders: SPIR-V.

    Vulkan allows us to use different interesting features. For example it allows to select the most appropriate GPU to use. It means no more crashes because of wrong GPU, I hope :) Also Vulkan supports multithreading.

    If you still have some time you could run the game with validation enabled. It makes the game slower but validates a lot more different internal things. It should help to make Vulkan stable for the release. To enable validation you need to add the following lines to your usef.cfg: 

    renderer.backend.debugcontext = "true"
renderer.backend.debuglabels = "true"
renderer.backend.debugmessages = "true"
renderer.backend.debugscopedlabels = "true"

    Known issues:

    • Screenshots aren't implemented yet, but going to be during Feature Freeze rP27552
    • Some precompiled shaders are missing, please report if the game says so
    • macOS isn't supported yet, but we have plans to do so via MoltenVk rP27488
    • Missing silhouettes rP27418
    • Unsupported depth formats cause an assertion rP27421
    • Stretching on window resize after fullscreen switch rP27422

  23. When starting the game in Gnome on wayland, the mouse can't reach part of the screen in full screen.

    This toy example seems to be working fine as long as I get the new window surface after changing to full screen.

    That's interesting. Could you add cursorbackend = "system" to your user.cfg (it should switch a cursor to the system one, "sdl" will bring it back)?

    You might just attach your example code here as an archive.

    Also are you able to compile the SVN version of the game? (I can provide patches to test.)
