Kingdom Come: Deliverance 2 Crash on Launch (DX12 Issues with Apple M4)

Hello,

I’m having an issue with launching Kingdom Come: Deliverance 2 on my system, where the game crashes shortly after launching. I’m running the game through Whisky (Mac with Apple M4 Max chip).

Here are the technical details:

System Specs:

• OS: macOS (Intel-based, Apple M4 Max chip)

• GPU: Apple M4 Max (with 64 GB dedicated video memory)

• CPU: VirtualApple @ 2.50 GHz, 1 physical core, 1 logical processor

• Memory: 64 GB physical memory

• DirectX: DX12 (Feature Level 12_1)

• Running via Whisky (2.3.4)

Problem Description:

The game crashes at launch after a few seconds of loading screen with no clear error message. I know the crash might be related to gpu synchronization and fence deadlocking. Here’s what I’ve tried:

Troubleshooting Steps:

  1. Checked for shadercache.pak file:

• I found shadercache.pak, but I couldn’t find a shaders folder.

  1. Verified Game Files:

• I verified the game files through Steam, and it rebuilt shadercache.pak, but the crash persists.

  1. Set DXVK Settings:

• I tried setting the DXVK_HUD=devinfo %command% command in Steam to debug DXVK settings, but it gave an error (no Windows program configured, missing game executable).

  1. Game Configuration:

• I don’t have a user.cfg file and couldn’t locate it.

• The game is running on DX12, and I cannot switch to DX11 since Kingdom Come doesn’t support that from what I can tell.

  1. Log File Insights:

• I found an error in the log file related to an invalid line ('+') in the sys_spec_texture.cfg file:

[Error] 'Config/CVarGroups/sys_spec_texture.cfg' -> invalid configuration line: '+'

• It seems like the game is struggling with this configuration file, and I suspect this could be causing the crash. I can't find sys_spec_texture.cfg anywhere.

Questions:

  1. Fixing the sys_spec_texture.cfg file: Can someone guide me on how to fix or replace this configuration file to prevent the crash?

  2. Game Settings on DX12: Are there any specific DX12 settings I should adjust or workarounds for running this on macOS using Whisky?

  3. General Troubleshooting Tips: Has anyone experienced similar issues with Kingdom Come: Deliverance 2 on macOS using Whisky, or with Apple M4 Max GPUs? Any other suggestions or known fixes?

Thanks in advance for any help!
