Why is my Ryzen 7 9700X choking in Dead Space 2 Remake?
Whenever I hit a corridor packed with Necromorphs, the gameplay just freezes for a millisecond. It felt like those old-school multi-core scheduling conflicts. I noticed my Ryzen 7 9700X was bouncing wildly between 3.8GHz and 5.5GHz, which sent my frame times swinging from 12ms to 35ms. I tried enabling 'Ultimate Performance' in Windows, but that was a total mistake—my CPU hit 92℃ and triggered a massive thermal throttle. I eventually went into the BIOS, set a PBO negative offset of 30, and manually locked the core clock at 5.1GHz. Using RTSS, I saw the frame time variance shrink from 15-40ms down to a tight 11-14ms. It wasn't a walk in the park, though; I had two random reboots right after the undervolt until I bumped the SoC voltage up by 0.02V. Now it stays cool between 68-75℃. AIDA64 stress tests confirm the scheduling is finally stable, with frame times locked in at 11-14ms.
