Dealing with frame jitter on Cooler Master Hyper 612 APEX in Stellar Blade?
The framerate was bouncing between 120 and 80 FPS, and that kind of tearing is absolutely brutal in a fast action game. After digging into the logs, I realized that if the Hyper 612 APEX isn't mounted with perfect pressure, you get a core delta of over 12℃, which causes random VCORE voltage drops. My first instinct was to turn on V-Sync in the driver panel, but that just added over 40ms of input lag; it felt like I was fighting underwater. I ended up stripping the cooler down, applying high-end thermal paste, and using a torque wrench to make sure the four corners were perfectly even. I also added a +0.02V offset in the BIOS. In RTSS, the frametime graph went from a jagged mess to a nearly flat line, hovering around 8.1-8.5ms. Ironically, the temps actually rose by 3℃ right after the remount, but once I flipped my case fan orientation to improve airflow, they settled at 68-74℃. The core delta is now under 6℃, and memory temps are stable at 58-63℃. No more crashes, just pure performance.
