REGRESSION: Icing has no aerodynamic impact

:wave: Thank you for using the Bug section, using templates provided will greatly help the team reproducing the issue and ease the process of fixing it.

Are you using Developer Mode or made changes in it?

No - observed with and without, screenshots with devmode to show sim parameters.

Have you disabled/removed all your mods and addons?

No, but no mods used affecting the tested aircraft.

Brief description of the issue:

Accumulated ice has nearly no physical impact. Except for some slow ice weight accumulation there is no additional drag or reduction in AOA, airplane flies with the same attitude.
I recall testing this several times in the past and it was affecting the aircraft significantly ( though still not enough to make it lose control as expected with total icing).
Aircraft left to graduatly ice up till the maximum icing condition .
Icing state at the end of the accumulation:
Option → Icing is at 1.0
Cell Ice Accum 1.0
Deicable parts Ice accum: 1.0

Provide Screenshot(s)/video(s) of the issue encountered:


Icing condition is at the maximum:

Custom severe storm:

Provide coordinates (DevMode > Options > Display position)

Irrelevant, used custom preset

Provide time & date of the observed Weather issue

Irrelevant, used custom preset

Detailed steps to reproduce the issue encountered:

Create severe icing stormy weather.

PC specs and/or peripheral set up if relevant:

Are you using DX11 or DX12?

DX12

Are you using DLSS?

No
