How to fix thread scheduling on i7-14700KF in MGSV?
While sneaking into enemy bases, I noticed these tiny frame skips that are absolutely lethal when you need precision. Checking the logs, the i7-14700KF was messing up the thread scheduling, dumping the main game process onto the E-Cores, which tanked the single-core performance. I tried the Windows High Performance power plan, but while the P-Core clocks went up, the scheduling error was still there—it's clearly an old engine compatibility issue. I finally went into the BIOS, disabled the E-Cores entirely, and set the process priority to 'Realtime'. In RivaTuner, my minimums jumped from 45 FPS to a steady 72-78 FPS, and the input lag vanished. The only downside was that Windows took longer to boot after disabling the cores, but enabling Fast Boot fixed that. CPU temps are around 65-72℃ at 120W. The performance is finally where it should be.
