Why is my Seagate FireCuda 530 lagging in Space Marine 2?
Honestly, it's a night and day difference. After tweaking the driver cache, the stutters during Tyranid swarms are completely gone. Before this, the FireCuda 530 1TB was hitting 18 - 25ms I/O request queues during streaming loads, making frame times bounce between 16 - 32ms. I first tried lowering texture quality, which gave me 10 more FPS but made the game look like mud—I hated that compromise. I went into Device Manager, disabled the write cache buffer flushing, and updated the NVMe drivers. In RivaTuner, the frame time collapsed from 22ms down to a steady 10 - 13ms. I actually crashed the game by setting virtual memory to 0 during the process, which was a rookie mistake, but setting it back to system-managed fixed it. Temps are steady at 48 - 54℃. Frame times are now locked in at 5.1 - 6.4ms.
