How to fix thread scheduling lag on MSI A520M-A PRO?
While swinging through NYC, I noticed the frame rate dipping from 90 down to 60 FPS, and it felt really jittery at high speeds. The VRMs on the MSI A520M-A PRO were jumping between 1.1V and 1.2V under load, causing CPU response delays of 12-18ms. I tried lowering the environment details first, which gained me 10 FPS but made the city look bland—it didn't fix the actual stutter. I went into the BIOS and set a CPU core voltage offset of +0.03V and switched Windows to the High Performance power plan. RivaTuner showed the frame times stabilize from 16-30ms down to 10-14ms. I actually messed up the memory frequency while I was in there and the PC wouldn't POST, but a CMOS clear fixed it. CPU temps are 72-78℃. After three hours of swinging, the drops are gone. Performance is finally verified.
