Why Single‑Thread CPU Loads Crash While Multi‑Threaded Loads Stay Stable – A Debugging Case Study
The article investigates intermittent crashes on an i9‑13900K when a single thread runs at full load, analyzes CPU voltage fluctuations, documents the debugging process using DirectXShaderCompiler, and demonstrates how converting a PSO warm‑up to multi‑threaded execution eliminates crashes and dramatically improves launch speed.
