# Dota 2 Vulkan crashes on launch in libnvidia-gpucomp.so on RTX 4090, Linux

## Summary

Dota 2 crashes on launch on Linux with Vulkan. The crash occurs inside NVIDIA’s userspace shader compiler, `libnvidia-gpucomp.so`, on Dota’s `Async Pipeline` thread.

This reproduces across multiple NVIDIA driver branches:

- 570.211.01

- 580.142

- 595.58.03

Current driver installed:

```text

NVIDIA 570.211.01

```

## Reproduction Steps

1. Launch Steam on Ubuntu 24.04.

2. Launch Dota 2 normally.

3. Dota starts briefly, then exits/crashes during Vulkan shader/pipeline setup before reaching the main menu.

Launch options:

```text

-novid

```

Steam also passes:

```text

+@panorama_min_comp_layer_dimension 0 -prewarm_panorama -novid

```

## Expected Result

Dota 2 launches to the main menu.

## Actual Result

Dota 2 crashes during Vulkan shader/pipeline setup before reaching the main menu.

## Diagnostics Already Tried

- Verified Dota game files in Steam.

- Cleared Steam shader cache.

- Cleared NVIDIA shader cache.

- Tested NVIDIA driver branches:

- 570.211.01

- 580.142

- 595.58.03

- Confirmed matching NVIDIA i386 libraries are installed for Steam runtime.

- Updated motherboard BIOS.

- Disabled Secure Boot.

- Disabled XMP.

- Tested conservative CPU limits:

- PL1: 125 W

- PL2: 188 W

- Confirmed `vulkaninfo` sees the RTX 4090.

- Checked kernel logs for NVRM Xid, MCE, machine-check, PCIe, and EDAC errors. None were present around the crash.
