Why is my Ultra 9 285K stuttering in GTA V FiveM sessions?
My frame rate was tanking from 144 down to 60 in crowded areas without any warning, which is a total nightmare during intense RP interactions. Looking at the logs, the Ultra 9 285K's hybrid architecture was messing up; FiveM's third-party scripts were being dumped onto the E-Cores, causing execution delays to swing between 18-32ms. I tried slapping on 'Ultimate Performance' mode in Windows, but that just pushed my CPU to 95℃ without fixing the drops—felt like a pointless compromise. I ended up going into the BIOS to manually limit the E-Core count and set the power plan to 'High Performance' to force the heavy lifting onto the P-Cores. Checking the frame time graph in RivaTuner, the spikes dropped from 15-40ms to a tight 9-13ms. It was a huge leap in smoothness. At first, my background apps felt sluggish after limiting the cores, but I sorted that out by manually adjusting thread priorities. Now the CPU stays between 68-75℃ with power draw around 110-130W. The scheduling glitch is gone, and the threading is finally fixed.
