Symptoms

When launching the game, it performs extremely poorly, consistently dropping to 5-6 FPS, making the game unplayable.

During this state, GPU usage remains at 0%, indicating that the game's main thread is blocked before it can send draw commands to the GPU. This behavior also causes the desktop environment to become sluggish, suggesting a total thread blockage.

The issue persists even with a clean Wine prefix.

Note: The performance slightly improves to 14-17 FPS when recording the screen with OBS Studio. This suggests that the game's performance is heavily influenced by CPU scheduling and power management states, which are altered when a resource-intensive background task like OBS is active.

Reproduction

Launch the game from Steam using the latest stable Proton version.
The game starts normally, but immediately drops to 4-6 FPS upon entering the main menu or gameplay.
The performance drop is consistent and reproducible every time the game is launched.
This performance issue occurs regardless of the Proton version used (tested on Proton Experimental, 9.0, and older versions).

In order to fix CPU bottleneck you need to disable 4G Decoding and Resizable BAR (ReBAR) in your bios found no command workround.

@illusioon can you try changing the game's launch parameter to DXVK_CONFIG="d3d11.cachedDynamicBuffers=a" %command% and see if it makes a difference?

In order to fix CPU bottleneck you need to disable 4G Decoding and Resizable BAR (ReBAR) in your bios found no command workround.

I have entered the BIOS and confirmed that 4G Decoding is currently disabled. However, it appears that the Intel Z270 chipset (ASUS ROG MAXIMUS IX FORMULA) does not have native support for Resizable BAR (ReBAR).

It is particularly strange that this bottleneck is occurring, as this issue is only happening with this specific game and not others. What makes this even more confusing is that I had already played about 4 to 5 hours of this game without any problems; it started happening from one day to the next.
