How to stop Intel i5 14600KF thread scheduling glitches?
The micro-stutters during high-speed driving were absolutely killing the experience for me. After digging into the logs, it turns out the Intel i5 14600KF scheduler was tripping up during high-concurrency scenes, dumping the main game thread onto the E-cores. This caused my frame times to jump wildly between 15-35ms. My first instinct was to just disable all E-cores in the BIOS, but that was a mistake—my multitasking tanked and boot times slowed down. I realized I needed a more surgical approach. I went into Windows Power Options, set the processor power management to High Performance, and used a process affinity tool to force the game to stay on the P-Cores. Monitoring with RTSS, the frame time graph went from a jagged mess to a flat line, with fluctuations shrinking from 12-40ms down to a tight 8-14ms. I even tried updating the motherboard microcode before this, but it caused two BSODs due to version conflicts. Once I rolled back and manually bound the cores, it finally stabilized. CPU temps are now a rational 65-72℃. Scheduling bug officially squashed.
