System specs: Intel Core i9-14900K CPU (24 cores) | 96 GB DDR5 RAM | RTX 4060 Ti GPU | NVMe SSD storage Results: – Opening the attached DOCX file containing ~13 000 text frames and ~4800 images took several minutes to load (similar to reporter’s experience). – During load, CPU utilization stayed high across multiple cores. Writer window appeared “Not Responding” for most of the process. – After the document finally opened, interface responsiveness returned, but scrolling and editing remained sluggish for several minutes.
