How to fix core scheduling lag on ASUS ROG Z890-A in Destiny 2?
The second I unleash a big ability, my FPS tanks from 144 to 60, and the judder is just brutal. I checked my telemetry and found the E-Cores on the ASUS ROG STRIX Z890-A were causing a 12-35ms scheduling delay on the main game thread. I tried 'Ultimate Performance' mode in Windows, but the CPU temps spiked 12℃, triggering a thermal throttle—just another useless fix. I ended up using Process Lasso to force the game onto the P-Cores and disabled E-Core sleep states in the BIOS. RTSS showed the frame time gaps shrink from 18-42ms to a steady 11-15ms. I did get some weird audio popping after the core bind, but switching the sample rate to 48kHz killed it. CPU temps are now 65-72℃ and VRAM is 52-57℃. The performance is finally where it should be.
