Why is my Ryzen 7 7800X3D scheduling poorly in Indiana Jones?
While sneaking around, my FPS stayed at 120, but I kept hitting these brutal 20ms micro-stutters every few seconds, which is a total nightmare during fast-paced action. Even with the 3D V-Cache, the core scheduling was struggling with complex physics, leading to thread migration delays of 8-15ms. I tried toggling Windows Game Mode, but that only tweaked the peak FPS without fixing the underlying scheduling mess, which felt like a waste of time. I eventually used a process manager to lock the main game thread to physical cores 0-7 and switched the power plan to High Performance. In RTSS, the frame time jumps of 5-25ms finally collapsed into a steady 7-11ms range, making the controls feel snappy. Early on, I noticed some system lag because background tasks were getting squeezed, but bumping the priority to High sorted it out. CPU temps sat steady at 62-71℃ with power swings under 12W. After running a performance analyzer, the scheduling lag is gone and frame times are rock steady at 7-11ms.
