Fixing loading delays on Jginyue B760M GAMING D4 in Yotei
Facing a 30-second black screen every time I start the game is absolute torture; it completely kills the excitement of playing. The BIOS on the Jginyue B760M GAMING D4 has some terrible UEFI compatibility lag, which was blocking SSD read commands for 120-180ms during the boot phase. I tried disabling all startup apps in Windows, but that only shaved off 2 seconds—a total joke of a fix. I eventually went into the BIOS, killed CSM compatibility mode, forced the boot priority to Windows Boot Manager, and turned on Fast Boot. Using a boot timer, the time from power-on to the loading screen dropped from 45 seconds to 18 seconds. I actually lost access to my old HDD after disabling CSM because it was MBR, so I had to convert the whole drive to GPT to get my files back. Board idle temps are 42-48℃ and the SSD is at 35-42℃. Saved all the tweaks via the BIOS export tool. It's a budget board, so these tweaks are mandatory.
