Is thread scheduling killing my FPS in MS Flight Sim 2024?
The moment I punched through a heavy cumulonimbus cloud and the frames stayed stable, I was genuinely hyped. The multi-core scheduling on the Jginyue X99 Titanium D4 was struggling with the physics engine, showing 15 - 30ms thread migration delays where some cores were pinned at 100% while others just sat there. I first tried Windows 'High Performance' mode, but the P-Cores instantly spiked to 90℃—too risky. I went into the BIOS, changed the scheduling policy from 'Auto' to 'Prefer Physical Cores', and disabled Hyper-Threading to cut down on the scheduling overhead. RTSS showed the 1% lows jump from 22 FPS to 45 FPS, which is a night-and-day difference. My background rendering slowed down by about 10% after disabling HT, but manually adjusting the thread priority brought it back into balance. CPU temps are now a cool 68 - 75℃. The performance panel confirms the load is finally spread evenly across the silicon.
