How do I fix input lag in Phantom Brigade with Crucial DDR4 RAM?

Combat felt unresponsive with 18ms frame delays. I lowered graphics settings, but the lag persisted. I used GamePP Hardware Sensor Page to set I/O priority to Manual Highest and switched to High Performance. GamePP shows frame generation now at 9-11ms, and I/O speed is stable at 3200MB/s. This verify step confirmed the fix was solid.
