Why is Black Desert Remastered stuttering on the B760M Gaming D4?
While exploring Calpheon in Remastered mode, I noticed these micro-stutters that were absolutely killing the experience. On a B760 board, this shouldn't happen, but after digging in, I found the default power-saving profiles were causing a 15-25ms wake-up lag on the bus during low-load transitions. I tried toggling High Performance mode in Windows first, but that was a waste of time; the bus latency stayed exactly the same. I had to go into the BIOS, navigate to Advanced $\rightarrow$ Power Management, and disable PCIe Link State Power Management, then set C-States to High Performance. Running AIDA64 showed latency dropping to 62-66ns, and the game finally stopped hitching. I did hit a snag where idle power jumped by 20W, so I had to tweak the voltage offset to find a sweet spot. VRM temps settled around 55-62℃. Exported the profile and it's rock steady now.
