Can adjusting PCIe link speed fix loading lag on Samsung 9100 PRO?
Riding across the wilderness, I noticed this weird stepped loading of distant textures, which is insane for a PCIe 5.0 drive. The 9100 PRO is a beast on paper, but my motherboard was negotiating it down to Gen4 or even Gen3, adding a 15-25ms lag to data transfers. I tried updating Samsung Magician first, but while the firmware updated, the link speed didn't budge—it was a waste of time. I went into the BIOS and forced the PCIe slot to Gen5 and disabled ASPM power management. Suddenly, sequential reads jumped from 7000MB/s to a massive 12000-14000MB/s, and textures just popped in instantly. I had some slow boot times after forcing Gen5, but disabling CSM mode sorted it out. Drive temps are sitting between 55-65℃ with the fan screaming at 2000-2200 RPM. The bandwidth choke is gone, but my case is definitely louder now.
