How to fix CPU thread scheduling on MSI MPG Z890 EDGE TI WIFI?
When fighting crowds, the physics engine slams the P-Cores to 100% while the E-Cores just sit there doing nothing. This imbalance caused my FPS to crater from 110 down to 45. The default voltage curve on this MSI board had a 0.05V drop during these spikes, triggering the CPU's frequency protection. I tried enabling 'Ultimate Performance' in Windows, but that just boosted P-Core clocks while increasing E-Core latency—a total fail that left me venting on forums. I finally went into the BIOS, set Load-Line Calibration to Mode 3, and locked the VCCSA voltage at 1.22V. In Cinebench R23, my multi-core score jumped by 800 points, and temps stayed around 78-84℃. I actually tried Mode 4 first, but the system rebooted three times until I dropped the voltage offset by 0.01V. Now, physics-heavy scenes stay between 90-105 FPS. I used the BIOS backup tool to save these settings, and the gameplay feels incredibly responsive now.
