I'm getting read latency and hitches during scene transitions. Should I check the read/write stability?

Walking through the forest scenes, I noticed the frame rate dipping from 60 down to 45. In a cinematic game like this, that's super noticeable. The Intel 760P 1TB hits 15 - 28ms latency spikes when fragmentation gets high, meaning assets can't load as fast as the GPU renders. I tried killing all background update services, which saved 500MB of RAM, but the hitches were still there—it didn't touch the root cause. I ended up forcing a system-level TRIM command and used an alignment tool to verify the 4K sector status. In the boot logs, scene load times dropped from 12.5s to 7.2s. I actually got a 'disk space low' warning during the TRIM process, so I had to wipe 40GB of temp files first. Temps are cool at 38 - 44℃. After three rounds of scene switching, the stutters are gone and memory temps are stable at 58 - 63℃.
