# Proton Experimental fixes Vulkan crashes in BeamNG.drive, Helldivers 2, DXVK-NVAPI issues

> **Key takeaway:** Valve's Proton Experimental update resolves game-specific regressions including Vulkan renderer crashes, anti-cheat compatibility, and DXVK-NVAPI misbehavior on non-NVIDIA hardware.

## Summary
Valve shipped a new Proton Experimental build on October 30th targeting compatibility fixes for several prominent Windows games running on SteamOS and Linux desktop. The update addresses a BeamNG.drive Vulkan renderer crash introduced by a recent game update, resolves random crashes in Helldivers 2 following its own update, and corrects a DXVK-NVAPI issue that caused Way of the Hunter 2 and other titles to malfunction on systems without NVIDIA GPUs. Additional fixes cover controller-related load time regressions in The Witcher 3: Wild Hunt - Remastered, mouse wheel input in METAL GEAR SOLID V: GROUND ZEROES, and GPU driver warnings on AMD hardware in Valor Mortis.

Two games—Gray Raven and Crown Trick—are newly rated as playable under this Proton Experimental build. The release continues Valve's practice of using Proton Experimental as a staging ground for changes destined for the next stable Proton version, currently Proton 11.0-2 with an 11.0-3 release candidate in testing.

## Compatibility layer fixes and affected subsystems
- **DXVK-NVAPI:** Fixed detection behavior causing games including Way of the Hunter 2 to fail on non-NVIDIA GPU setups where dxvk-nvapi was present but non-functional.
- **Vulkan renderer path:** Resolved crash in BeamNG.drive specifically triggered after a recent game update, indicating Proton-side adaptation to changed engine behavior.
- **Anti-cheat and online titles:** Addressed random crash regression in Helldivers 2, a live-service title with anti-cheat requirements, suggesting continued Proton maintenance around kernel-level and user-level anti-cheat compatibility.
- **Input and HID subsystem:** Fixed long load-after-death times in The Witcher 3: Wild Hunt - Remastered when game controllers are connected, pointing to a Proton input/polling interaction with the game's checkpoint system.
- **AMD GPU path:** Eliminated spurious driver GPU warning in Valor Mortis on AMD graphics hardware, reducing false-positive compatibility friction for RADV users.

## Why it matters
These fixes directly improve the experience for Steam Deck owners and desktop Linux gamers running AMD GPUs, where DXVK-NVAPI misdetection and spurious driver warnings are common friction points. The continued rapid turnaround on game-specific regressions—particularly for live-service titles like Helldivers 2 with anti-cheat dependencies—demonstrates Proton's maturation as a sustained compatibility platform rather than a one-time translation layer, reinforcing Linux as a viable daily gaming OS.
