Why does my ASUS TUF B760M drop frames during fast swings?
When swinging fast between Manhattan skyscrapers, the CPU power draw jumps wildly between 120W and 180W, causing a 110-140mV voltage drop on the 12V rail. This sent my frame rate plummeting from 110 FPS down to 45 FPS. I first tried enabling Ultimate Performance mode in Windows, but that software-level tweak did absolutely nothing for hardware-level voltage instability—it just bloated my idle power draw, which was incredibly frustrating. I eventually dove into the BIOS, navigated to Advanced Power Management, and switched the Load-Line Calibration (LLC) from Auto to Level 3, while setting the CPU Core Voltage Offset to -0.050V. Checking HWInfo in real-time, the voltage ripple tightened from 130-160mV down to 40-65mV, and the frame times finally flattened out. I actually hit two boot failures during the first LLC attempt, and things only stabilized after I bumped the memory voltage by 0.02V. The VRM temps stayed around 52-58℃, and the heatsinks felt warm to the touch. After a three-hour stress test, the voltage output is back to baseline with frame times locked at 5.1-6.4ms. It's a relief, though the BIOS menu is a nightmare to navigate.
