Title: Diagnostic Analysis and Remediation of “Unhandled Exception Caught” During Initialization in Call of Duty: Black Ops II
Abstract This technical paper addresses the critical initialization failure in Call of Duty: Black Ops II (Treyarch, 2012) characterized by the error message: “Error during initialization - Unhandled exception caught.” This paper outlines the technical etiology of the error, distinct from standard crashes, identifying it primarily as a conflict between the game’s DirectX 9 rendering requirements and modern system architectures (DirectX 11/12 hardware), specifically regarding Multi-Channel Sample Anti-Aliasing (MSAA) and threading concurrency. Verified solutions ranging from configuration file manipulation to driver-level enforcement are detailed.
If you are using an AMD GPU or a laptop with hybrid graphics (NVIDIA Optimus or AMD Switchable Graphics), the error may read "Unhandled exception caught" because the game cannot decide which GPU to use. Ensure Windows is fully updated (Settings → Update
