Game crashes and graphical glitches in Uncharted 3 (CUSA02343) during specific events (London Bar Fight).

Technical Positioning
Game stability, visual fidelity, robust error handling.
SaaS Insight & Market Implications
This issue details severe game crashes and graphical glitches (vertical/angled lines) in Uncharted 3, specifically during the 'London Bar Fight' event. The crash log points to a 'read access to ffffffffffffffff' fault, indicating a critical memory access violation. This suggests deep-seated instability within the game's memory management or rendering pipeline, potentially exacerbated by specific game states or hardware configurations. The mention of Vulkan extensions (`VK_AMD_shader_explicit_vertex_parameter`, `VK_EXT_shader_stencil_export`) and a workaround involving `BB_GPU_MERGE` points to GPU-specific rendering issues. Such reproducible crashes and visual defects are critical blockers for user progression and severely undermine product stability and user trust.

Uncharted 3 (CUSA02343) Crash Event: London Bar Fight

First of all, there are graphical glitches, like vertical & angled lines popping up in specific areas. I am pretty sure that is not shader related as it can be reproduced.

Same error on my pc too

same
kunalsaw57 • Oct 16, 2026
Found a workaround, used this and it is working now. use powershell and give correct path to Unchared.exe $env:BB_GPU_MERGE = '0' & 'G:\Uncharted\uncharted-windows\Uncharted.exe'
