How to fix I/O scheduling delays on Galax B760M for Lost Ark?
Running Lost Ark on this board felt like trying to drive a tractor on a highway—the performance gap was just ridiculous. The PCIe 4.0 lanes on the Galax B760M Black Knight were hitting scheduling delays between 18-35ms during heavy texture streaming, which caused those annoying frame drops when entering new zones. I tried messing with the virtual memory extension, but that was a total placebo; it didn't change a thing. The real fix was in the BIOS: I disabled PCIe Link State Power Management and turned off Fast Boot to make sure the hardware fully initialized on startup. After these changes, my CrystalDiskMark 4K random reads jumped from 52MB/s to 68MB/s, and the loading hitches mostly disappeared. I did run into a weird bug where the SSD wouldn't be recognized instantly on boot after disabling power management, but switching Windows to the 'High Performance' power plan killed that issue. Now the board stays cool at 46-53℃ and the I/O throughput is finally consistent, with fans humming at 1400-1600RPM.
