My Intel 760P 2TB has read speed swings that cause Fortnite to stutter or crash during scene loads. Should I tweak this?

Having the loading bar freeze at 90% for ten seconds is pure torture; it felt like I was back on a mechanical HDD from the 90s. The Intel 760P in the primary M.2 slot was occasionally being misidentified as Gen2 in 'Auto' mode, causing reads to tank from 2000MB/s to 1000MB/s. I wasted a good hour swapping the drive to the second slot, only to find that slot runs through the chipset, which actually added 10ms of latency. The real fix was going into the BIOS and forcing the PCIe mode to Gen3 instead of 'Auto', then updating to the latest manufacturer firmware. CrystalDiskMark confirmed sequential reads climbed back to 2100 - 2200MB/s, and scene loads dropped to about 5 seconds. I did have a scare where the drive wasn't detected after the firmware flash, but a quick reseat fixed it. Drive temps stayed cool at 40 - 46℃. Checking the system logs, the I/O throughput is finally hitting the mark, and the input response feels rock steady.
