Is the Intel 660P 2TB cache causing RDR2 lag spikes?
Every time I ride fast into a new town, the loading bar just hangs at 70% for a few seconds, which completely kills the immersion. The Intel 660P 2TB's dynamic cache is the culprit; once it fills up, write speeds tank from 3000MB/s to under 800MB/s, causing these brutal loading hitches. I tried setting a fixed size for my virtual memory, but that actually made the I/O conflicts worse in this open world, and the stuttering got even more frequent—pretty stressful trial and error. I eventually went into the device settings and pushed the NVMe queue depth from 1024 to 2048 and enabled the forced write cache flush in the performance options. CrystalDiskMark showed 4K random reads improving from 40-50MB/s to 60-68MB/s, and scene transitions dropped from 15 seconds to about 7. I did hit a snag where the drive had a detection delay during boot, but switching to the High Performance power plan cleared it up. Temps are sitting at 45-55℃ with a basic heatsink. It's finally usable.
