I'm getting instant read/write delays and stutters during combat in Alan Wake 2 with a FireCuda 530 500GB.

During those intense psychological combat scenes, the game would just freeze for 0.2 seconds, which is terrifying when you're on edge. I found that the FireCuda 530 was jumping between 1.2-1.4GHz when switching between low and high loads, causing packet delays. I tried dropping the PCIe protocol to 3.0; the stutters stopped, but I lost the 4.0 speed advantage, which felt like a bad compromise. Instead, I went into the BIOS and locked the PCIe voltage to a stable 1.08V, keeping the drive at 48-54℃. It still had some wobbles until I disabled the CPU C-States in BIOS. Now the CPU stays at 65-71℃ with fans at 1500 RPM. After three rounds of random R/W stress tests, it passed with zero errors. The drive is stable at 48-54℃, but the power draw is slightly higher.
