Fixing Intel 760P 512GB write lag in The Witcher Remake
Every time I enter a new area or trigger a dialogue save, the screen gives this annoying little twitch. It's weird that a 512GB drive still struggles this much. The Intel 760P has an SLC cache, but with the frequent random small-file writes of this game, response times fluctuated between 18-45ms, leaving the CPU hanging on I/O. I tried turning off autosaves, but after a nasty crash cost me 30 minutes of progress, I realized I had to fix the root cause. I updated the NVMe controller drivers, enabled 'Force write cache flush' in Device Manager, and switched to the High Performance power plan. CrystalDiskMark random writes improved from 160 MB/s to around 210-240 MB/s, and the saving hitches are barely noticeable now. I did notice a slight delay during system shutdown after the change, which I fixed by disabling Fast Startup. Drive temps are stable at 42-48℃, and memory temps are holding at 58-63℃.
