Arc Raiders Linux Fix (Proton)

Problem

Arc Raiders crashes on startup with AMD GPUs (RADV driver) due to a Mesa bug with vkCreateComputePipelines.

Error:

wine: Assertion failed at address 00007F... (thread 0088), starting debugger...
!status && "vkCreateComputePipelines"

Related Issues:

• Proton #9164
• Mesa #14225

Fix

This patch removes crash-causing assertions in Wine's Vulkan layer, allowing the game to continue even when pipeline creation returns an error.

v2.0 now patches multiple Vulkan functions:

• vkCreateComputePipelines
• vkCreateGraphicsPipelines
• vkCreateRayTracingPipelinesKHR
• vkCreateShaderModule

Requirements

• Linux with Steam installed
• Proton Hotfix (or other Proton version)
• xxd and objdump (usually pre-installed)

Installation

Standard (Recommended)

chmod +x patch_winevulkan.sh
./patch_winevulkan.sh

Aggressive Mode (if still crashing)

./patch_winevulkan.sh --all --verbose

Options

Flag	Description
--all	Patch ALL found Vulkan assertions (more aggressive)
--verbose	Show detailed patching info
--restore	Restore from backup

Usage

1. In Steam, right-click Arc Raiders → Properties → Compatibility
2. Select "Proton Hotfix" (or whichever version you patched)
3. Launch the game

Recommended Launch Options

If you experience crashes or recording issues:

PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%

Debugging

If you still have issues, enable logging:

PROTON_LOG=1 %command%

Check ~/steam-*.log for errors.

Reverting

The script creates a backup. To restore:

./patch_winevulkan.sh --restore

Technical Details

The patch replaces jne instructions (opcode 75 09) with two nop instructions (90 90) at locations where Vulkan functions would trigger assertion failures.

Before: test %eax,%eax; jne assert_fail
After: test %eax,%eax; nop; nop
