Another windows screenshot:

Now I see the animation of wings on DXVK is too fast, like 3-5 times faster than on native Windows.

What exactly is wrong about the wings? Looks absolutely identical to me in your screenshots.

I think i understand what he is talking about.

So it's a depth sorting issue?

@CME42 says this is a depth bias issue on nvidia

It also occurs on my rx5700 XT card, while using AMDGPU.
You can still encounter it on newest proton (7.0-1 by time of writing this comment).

-- Update:
It works fine on Intel HD4000 modesetting driver.

I tried reproducing this on my R9 380 and mesa git, but i've been unable to. Is it only certain wings?

There are two issues here, one is depth bias on nvidia and one is some fixed function fun, i have an nsight trace locally here where it's reproducible.

But the OP has a AMD GPU.
Maybe i misunderstand what the Nvidia specific issue is

Yeah i just got myself confused back then, there is also a depth bias problem on nvidia, but on AMD it's only some fixed function stuff.

Roger. At least i didn't notice the wings Infront issue when i tested with 1.7.2. and mesa git.
But I'll try to find the correct wing type just to make sure.

Apparently it's not completely fixed.
