Why does Resident Evil 9 stutter when opening doors with ADATA RAM?

I was so excited for this game, but scene transitions were choppy. I first tried updating to Beta drivers, but the stutters remained and I got weird purple artifacts—a total nightmare. I used the GamePP Shader Compilation Queue Manager to wipe 5.8GB of old cache and forced a re-compile. Frame times stabilized at 12-16ms per GamePP, memory temperatures stayed at 44-50℃ per AIDA64, and fan speeds stayed at 1300 RPM per HWMonitor.
