Banishers keeps freezing for a few seconds during the initial scene load on my H510M, why is this?

The second I tried stepping into New Eden, I hit a wall—the loading bar just sat there at 99% for about 5 seconds. It happened every single time I rebooted, which was incredibly annoying. It turns out the Soyo SY-King Dragon H510M has some clunky boot logic when handling NVMe fast boot while CSM (Compatibility Support Module) is enabled, triggering useless hardware checks. I first tried disabling all non-essential startup items in Windows, but that only shaved off one second and the game still felt glitchy. I eventually dove into the BIOS, nuked the CSM mode entirely, and forced a pure UEFI boot. I also disabled the PCIe Link State Power Management to stop the drive from sleeping. Checking the system logs, my boot time dropped from 12.4s to 6.8s, and the game freezes vanished. One heads-up: after disabling CSM, my drive disappeared from the boot list until I converted the partition table from MBR to GPT. VRM temps stayed around 55-62℃. After several cold boots, the loading curve is finally rock steady.
