Fixing bus frequency lag for Great Wall GW3300 in Hitman 3
Nothing ruins a perfect stealth run like a random frame drop. I checked the backend and found the NVMe bus was choking for about 0.4 seconds, causing the clock speed to plummet. I realized I'd been too aggressive with the PCIe Link State Power Management to save energy, and the wake-up latency was killing my performance. That obsession with efficiency was a total trap. I went into the BIOS, killed all link power savings, and forced the PCIe speed to Gen 3. Suddenly, random R/W latency was pinned at 1.2-1.8ms, and frame intervals dropped from 19.4-27.1ms to 12.8-15.2ms. I tried adding virtual memory at first, but that just created a massive disk conflict. Once I moved the game to a dedicated partition and realigned the sectors, the stuttering vanished. The drive still hits 70-74℃ under full load, but as long as the response is instant, I'm happy. I switched the mode to 'High Performance' in the management tool, and frame times are now rock solid at 12.8-15.2ms.
