Micro stuttering when using abilities.

[semmi]

I have issues with the game creating frames with longer creation times leading to annoying micro stuttering when using an ability.
Abilities that proc something make it worse.

Disabling addons makes no difference.

I tried it on Windows 10 and Arch Linux with D3D9, DXVK on both or Wined3d with the same results.
On Linux it is slightly worse despite higher average fps usually compared to Windows, making melee specs less fun to play. Especially abilities that proc additional damage and buffs create frametimes of up to 60ms while my average frame times are below 5ms. On my 120Hz display this shows as a 5-6 frames freeze.
It does not happen when other people are doing something. When I just watch other characters the frame times stay constant.

Here are videos I recorded with a frame time graph to showcase this issue.

My CPU is an AMD 5800X3D and my GPU is an AMD 7900 XT.
I am using the most recent AMD drivers for chipset and GPU on Windows 10, most recent Arch linux-zen 6.10 kernel and wine 9.13.
Both recordings are with DXVK 2.4, but I also tried it with Windows default D3D9 and used MSI Afterburner for the frametime graph with the same results.
To get a graph with DXVK one can add

dxvk.hud = devinfo,fps,frametimes

to the dxvk.conf in the Ascension client's folder.

Can anyone reproduce this? Can it be fixed?
