How to fix WD Black SN770 2TB PCIe link instability in Indiana Jones and the Great Circle?

Exploring Indiana Jones felt broken as my WD Black SN770 2TB link jumped between Gen4 and Gen3, causing massive stutters. I tried reseating the drive, but system recognition became unstable. Using GamePP Hardware Sensor Page, I detected voltage drift and recalibrated the slot to +0.01V to force a Gen4 x4 lock. CrystalDiskMark confirmed stable read speeds at 6800-7200MB/s. Map loading dropped from 15s to 5s, effectively fixing the open-world lag and ensuring smooth asset streaming.
