Vulkan - new graphics API

It does "inverse" stretching, ie reducing width makes stretching worse.

Did you experience any performance difference?

Max settings, first screen of campaign :
OpenGL ARB ~145fps
OpenGL ~127fps
Vulkan ~98fps

Thanks! Is that without any renderer.backend.debug*, right?

Maybe time to update shader mod so as not to loose track which were already reported and allow me to test decent looking water. *wink*

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

I also got some errors. I just atach the interesting log.

interestinglog.html

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.

**hyperion** · January 12, 2023

There are some shadow like artifacts (map nubian frontier)

Which behave strangely when zooming in

Could you run the game with validation enabled?

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.

I already do, but don't get extra output unlike with gl. Anything you want me to look out for / you expect to see?

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

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

Then it seems the known problem of broken materials.

Attached patch fixes it for me, tho there might be many more similar ones out there. I don't understand the issue, so I won't write a validator ...

First you need to download it by the link in the first message and then install just like every other mod.

Leyto · January 13, 2023

Hello @vladislavbelov, and everybody,

is it possible to test this mod with a 0AD installed through windows installer, or does it require to use the SVN version of the game?

Currently no, but we plan to make an RC relatively soon and it'll be bundled with this mod.

Leyto · January 13, 2023

Ok thanks. I guess I'll get the game through SVN, can't wait more to test it!
Should we expect some visual awesomeness/differences, or it's more a performance boost targetted with this API ? (which is also welcome of course )

Not yet.

The first step is to reduce the number of driver dependent bugs and crashes and to have a more predictable performance.
