What

The GPU selector accepts a discrete adapter with graphics, compute and presentation queues before checking its required BDA features. WSL's Dozen adapter for an RTX 3060 is selected despite lacking VK_KHR_8bit_storage, so device initialization fails instead of using the available compatible lavapipe device.

Probe the existing byte-storage and buffer-device-address requirements before accepting each candidate. Log the rejection reason and continue selecting among compatible adapters. Explicit ANYPS5_GPU filtering still applies. Document the selection requirements.

Tested

Ubuntu 26.04 under WSL, Intel i7-11370H, Mesa 26.2.4. Full relinker and patched system-library build completed.

• agc_driver_device_selection passed with Dozen and lavapipe both installed; the unsupported NVIDIA and Intel Dozen adapters were skipped.
• agc_driver_bda_device passed with VK_DRIVER_FILES=/usr/share/vulkan/icd.d/lvp_icd.json (the default adapter skips this test because it lacks byte storage).
• Eight existing tests covering guest exception handlers, raised exceptions, address synchronization, _umtx_op, guest module directories and Intel conversion passed.
• Conventions and git diff --check passed.
• 7 Days to Die - Console Edition (PPSA16645) rendered its loading screen and reached the license-agreement screen with automatic lavapipe selection. A five-minute run and a subsequent six-minute run completed without the startup abort, ending at the configured time limits. The agreement was not accepted. Gameplay and online services are not verified; this is not a full compatibility claim.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw; no silent stubs added
• No notes, investigation files or images added to the repository
• No new third-party code
• Generic behaviour, not specific to one title
• Depends on: none
• Unblocks: PPSA16645 startup GPU selection; no existing Game bring-up discussion found; gameplay remains unverified
• AI-assisted: yes, with Codex
