My game keeps freezing at the loading screen with a Great Wall GW3300. Is this an I/O block?

Every time I enter a new dialogue area, the loading bar just hangs at 90% for ages. It completely breaks the game's rhythm and honestly made me super anxious. The Great Wall GW3300 only hits about 2,000MB/s sequential reads, and it was clearly choking on high-res texture streaming, causing severe I/O blocking. I tried dropping the texture quality to 'Low', but the game looked like a blurry mess, which was a compromise I just couldn't make. I then used a partition tool to verify 4K alignment and disabled the 'Fast Startup' power-saving options for the drive in the power plan. CrystalDiskMark showed random reads climbing from 32-38MB/s to 45-50MB/s, and load times dropped from 20 seconds to 11 seconds. Weirdly, the first alignment tweak slowed down my boot time until I reconfigured the boot order. Now the drive stays between 38-45℃ and the chipset is at 52-58℃. The performance analyzer shows a smooth throughput curve, and the input lag is finally gone.
