How to fix thread scheduling lag on MSI MPG Z890 EDGE TI WIFI?
Building complex ray-traced cities was a total nightmare, with frames swinging wildly between 120 and 40 FPS. I initially thought it was a GPU driver glitch and chased a Beta update, but that just made the stuttering worse. After digging into the core loads via HWiNFO, I realized the MSI MPG Z890 EDGE TI WIFI was dumping heavy ray tracing tasks onto the E-cores while the P-cores were basically idling. I dove into the BIOS Advanced menu and manually forced the core scheduling priority to Performance, then locked the minimum processor state to 100% in the Windows Power Plan. Using a frame time analyzer, I saw the frame intervals tighten from a messy 8.2-22.5ms down to a rock steady 4.1-6.8ms. My idle power draw jumped by about 12W at first, which was annoying until I tweaked the E-core sleep states. Now the CPU stays between 62-68℃ and feels incredibly responsive. I used the motherboard utility to export this profile so I don't have to do this again.
