How to fix Seagate FireCuda 540 bandwidth spikes in BF V?
In the middle of a firefight, every time I flicked my view, the FPS would bounce between 70 and 100. It felt jittery and ruined my aim. The Seagate FireCuda 540 2TB has a fast cache, but under PCIe 4.0 loads, the cache refresh cycle was fluctuating between 15-35ms, causing uneven data delivery. I tried enabling 'Game Mode' in Windows, but it did nothing—just another useless software toggle. I finally went into the driver panel, changed the cache flush policy from 'Auto' to 'Manual', and updated the NVMe driver to the latest version. In RTSS, the frame time variance shrank from a 20-40ms range to a tight 22-28ms. The smoothness is night and day. My SSD temp did climb from 52℃ to 65℃ after the tweak, so I had to crank up my case fans to compensate. Now it runs at 58-65℃ with the heatsink at 48-55℃. The game finally feels responsive to my inputs.
