Does the Sapphire RX 7800 XT have driver scheduling issues in city ruins in TLOU Part II, and how to fix it?

Walking through the ruined streets, the game would just randomly freeze for a split second, which is incredibly jarring on a high-end card like the Polar Edition. The core clocks on my Sapphire RX 7800 XT were bouncing between 1800 - 2200MHz, causing frame times to jump from 16 - 32ms. I tried updating the drivers, but the latest version actually made the game crash more often—a total waste of time. I decided to manually override the power curve in Adrenalin, bumping the power limit by 10% and locking the minimum frequency at 2000MHz to stop the clock jumping. In AIDA64 stress tests, the FPS variance dropped from 15 frames down to just 3. The card did draw about 25W more, and I had to make the fan curve way more aggressive to keep it cool. Core temps are now sitting at 68 - 74℃, and the scheduling feels way more consistent now.
