How to optimize Intel 760P bus frequency for Battlefield 2042?
Nothing ruins a firefight like a sudden frame drop. I checked the logs and found the NVMe bus was blocking for about 0.4 seconds, causing the clock speed to plummet. Looking back, I'd set my PCIe Link State Power Management to be way too aggressive to save a few watts, which created massive wake-up latency—my obsession with efficiency was killing my game. I went into the BIOS, killed all link power savings, and locked the PCIe speed to Gen 3. My sensors showed random read/write latency clamped at 1.8-2.5ms, and frame intervals dropped from 20.4-31.1ms to 14.2-17.5ms. I tried increasing the page file size first, but that just caused disk thrashing; it only got smooth after I moved the game to a dedicated partition and realigned the sectors. The drive still hits 65-70℃ under load, but as long as the response is instant, I'm happy. Switched the mode to High Performance, and temps are steady at 65-70℃.
