How to fix PSU ripple causing lag in CS2 on Huntkey T600?
Man, swapping the cables was a game-changer—my minimums jumped by 20 FPS! With the Huntkey Blizzard T600, I noticed that in high-refresh scenarios (300+ FPS), the 12V rail ripple hit 85mV, which caused micro-stutters in the GPU core voltage. I first tried capping the FPS at 144 in the driver, which stopped the drops but added a noticeable amount of input lag, which is a total dealbreaker for a competitive shooter. I swapped the single 8-pin daisy-chain cable for two independent PCIe cables and redistributed the peripheral load. Using an oscilloscope, I saw the ripple peak drop from 85mV to 32mV - 40mV, and frame times tightened from a messy 3-12ms to a clean 2-4ms. I actually had a boot failure at first because a modular plug wasn't seated right, but once I locked it in, it was solid. PSU internal temps are 42℃ - 48℃ and it's whisper quiet. Frame times are now locked at 5.1ms - 6.4ms.
