I am getting sudden speed drops and frame hitches during scene transitions in Crimson Desert on my FireCuda 530. Should I lock link speed?

The moment the open plains load, my FPS crashes from 100 down to 40. It was infuriating, but it helped me find the culprit. The default link policy on the FireCuda 530 was causing 22-30 ms sync delays during heavy requests, making the 1% lows plummet. I tried dropping the game to low settings, but while I gained 12 FPS, the game looked like a blurry mess, which was a non-starter. I went into the BIOS, forced the PCIe link speed to Gen 4, and tweaked the Vcore voltage from Auto to 1,21 V, while disabling all power-saving states. Using a frame time analyzer, the jitter dropped from 25-55 ms down to 8-15 ms, and the smoothness came back instantly. My first attempt at locking the max frequency caused a BSOD on the loading screen, but stabilizing the voltage fixed it. Temps are 55-62 C, and frame generation is now a steady 5,1-6,4 ms.
