Talos Principle 2: stutters when passing through force field effects

As can be seen, when the player's avatar passes through force field (violet field), or force field animation is being played (blue fields), the game stutters with very noticeable frame drops.

A few months prior I've finished the game fully, and noticed no such issues.

Might be an issue with the Wine\Proton itself, as per ValveSoftware/Proton#7237 (comment)

I've tested two different versions of Proton from 8.0 branch, and it seems that this issue is not present with them.

For any tester trying to reproduce this should make a VKD3D_QUEUE_PROFILE. Maybe there's something actionable in there.

No stuttering here with 6900XT, using current master for mesa, proton bleeding-edge, and vkd3d-proton.

After coming back to the game I experienced the same kind of stuttering that I hadn't had before.

From my testing it related to having a controller connected when playing. When I unplugged the controller in between a game restart the stuttering disappeared. Here's a recording of it happening. As you can see the first two clips show the exact stuttering, but in the third clip it's completely gone.

So I don't think this is a vkd3d issue. I will post this in the other thread here ValveSoftware/Proton#7237 (comment).
