Why does Fortnite stutter during fast building with Gloway DDR5?

I felt absolute desperation during fast-paced building firefights when I noticed read/write latency jumping between 72-85ns per AIDA64, causing micro-stutters that ruined my competitive flow. I tried increasing virtual memory to 24GB, but it didn't alleviate the drops and instead caused disk read/write conflicts. I then used the GamePP Resource Scheduler to force the game process to Realtime priority and disabled background services. Frame generation time finally stabilized at 6-9ms per RTSS, and memory temperature stayed at 44-50℃ per AIDA64.
