How to stop UE5 from choking on Crucial DDR4 2400MHz 8GB?
While running the Matrix demo, every time I panned the camera quickly, the screen would tear and freeze, which was honestly baffling. The bandwidth on this Crucial DDR4 2400MHz 8GB kit is just way too narrow for massive geometry data, with memory usage hitting 97% - 99% instantly, forcing the system to lean on the slow disk swap. I tried killing all background services first, but even in a clean environment, the RAM stayed at the breaking point; that kind of cleanup is useless against raw capacity limits. I eventually manually set the virtual memory to 32GB and forced it onto a high-speed NVMe partition, then bumped the engine process priority to 'Realtime' in Task Manager. In the profiling panel, the page file read/write frequency stayed high, but at least those second-long freezes stopped. I actually hit two nasty disk I/O conflicts early on, which only cleared up after I disabled Windows Fast Startup. RAM temps hovered around 42℃ - 46℃, and the SSD stayed between 52℃ - 58℃. System Monitor confirms the resource curve is finally flat, with frame times sitting steady at 5.1ms - 6.4ms.
