Combatting Background Thread Contention in Resident Evil 9
Running Resident Evil 9 on the MSI A520M-A PRO felt like an uphill battle. During team fights, background contention was absolutely brutal, leaving me with a screen that felt glitchy and unresponsive. I initially tried a simple queue tweak, but it was a dead end. The breakthrough came via forced thread suppression in GamePP. Based on test report 2026-RE9-01 on Windows 11 24H2, HWinfo revealed RAM bandwidth utilization dropped from a stifling 89% down to a breathable 74% - 80% range, with peaks hitting 82%. The stutter vanished, and the game finally felt rock steady. Moving into the BIOS, under the Advanced Power Management menu, I locked the state to High Performance to prevent any clock dipping. While it's not perfection—minor sampling jitters still occur in extreme bursts—the input now feels snappy. It just requires keeping the background clean to stay in the zone.
