Why is my Ultra 9 285K hitching in Fortnite combat?
The moment I started building fast, my frame rate just went wild, and that stuttering was a total nightmare. The new architecture on the Ultra 9 285K was bouncing tasks between P-Cores and E-Cores like crazy, causing my frame times to jump randomly between 6.2ms and 14.8ms. I first tried disabling all the E-Cores in the BIOS, but that was a mistake; my 1% lows tanked from 140 FPS down to 110 FPS, which felt like a huge step backward. I eventually used a process affinity tool to force the main game thread onto the P-Cores and switched my Windows power plan to Ultimate Performance. Watching the RTSS overlay, the frame time graph went from a jagged mess to a flat line. I actually blue-screened twice while messing with registry scheduler weights, but once I bumped the delay from 0 to 1, it finally locked in. My CPU temps stayed between 62-68℃ with a super even load. According to the performance analyzer, my 1% lows jumped by 22%, and frame times are now rock steady at 5.1-6.4ms.
