Analyzing performance bottlenecks in Like a Dragon Ishin
Oddly, throughput was maxed, but 1% lows jumped wildly between 30-45 FPS. Checking the I/O queue proved storage wasn't the issue—it was core scheduling. Windows Performance Monitor showed Core 0 pinned at 95%+. I entered the BIOS -> Advanced Power Management, disabled energy-saving states, and offset the core voltage to -0.020V. In 3DMark, the frame time curve shifted from a sawtooth to a flat line with less than 2% deviation. While average FPS barely moved, the screen tearing vanished. Note that CPU transient power rose, making the fans noticeably louder.
