How to fix E-core scheduling issues on the i5-13490F?
The moment a dimension jump hits, the screen just hitches out of nowhere, and that inconsistent frame pacing is a total nightmare for anyone chasing a fluid experience. After digging into HWiNFO, I spotted that the Intel Core i5-13490F was dumping the main thread onto the E-Cores during asset decompression, causing the instruction pipeline to swing wildly between 12-45ms. I tried slapping on the 'Ultimate Performance' power plan first, but that was a joke—CPU temps jumped 10℃ and the stutters didn't budge. I eventually used Process Lasso to force the game process onto the P-Cores and disabled the E-core automatic sleep state in the BIOS. Checking RTSS, the frame time variance collapsed from a messy 18-42ms down to a tight 11-15ms range. I did hit a snag where the audio started crackling after the first core affinity tweak, but fixing the sample rate to 48kHz cleared it up. Now the CPU stays chilled at 65-72℃ with no frequency diving. I saved the whole profile in the motherboard utility so I don't have to do this dance again.
