Symptoms

Game has slightly static-y sound, and noticeable input lag, both in-game and in-menu.
In-game, immense lag is immediately noticeable, making game unplayable.
As an aside, I have tried disabling Esync, Using WineD3D, and disabling D3D11. None improved performance.

Reproduction

1. Start game.
2. That's basically it, you'll notice problems immediately.

Reproduce Captain Forever Trilogy from Steam using Proton 3.16-4, then inspect the attached steam-758930.log alongside the reported static audio and input lag. Compare the launch attempts mentioned in the report, including Esync, WineD3D, and D3D11 changes; done means identifying and resolving the compatibility problem so the game is playable without the reported lag and sound issues.
