How to calibrate storage performance for the Hunt Tech Demo?
Watching distant mountains load in like low-res pixels was infuriating; I honestly thought I was out of VRAM, and the anxiety peaked after a few major frame drops. It turns out once the SLC dynamic cache on the FireCuda 540 2TB fills up, read speeds plummet from 7000MB/s to under 1200MB/s, meaning the assets can't keep up with the render. I tried increasing the page file size, but that just created more I/O conflicts in the tech demo, making the stutters worse. I went into Device Manager, pushed the NVMe queue depth to 2048, and enabled the forced write-cache flushing policy in Windows performance options. CrystalDiskMark showed 4K random reads jumping from 45-52MB/s up to 68-75MB/s. I hit a brief drive recognition lag during idle after the queue tweak, but switching from Balanced to High Performance power mode cleared it up. Temps stayed in the 42-55℃ range. Redefining the R/W strategy finally got the parameters dialed in.
