How do I stop the 2-second black screen when switching from ruins to base in Human Host?

Switching to the base froze my screen for 2 seconds, a painful lag in the open world. I tried updating the chipset driver, but the issue remained. I used GamePP Peripheral Driver Conflict Detection to disable conflicting services and reset the storage driver, then set queue depth to 1024. CrystalDiskMark showed I/O latency dropping from 15ms to 8ms, with memory temps at 58-63℃ per AIDA64 and drive temps at 45-50℃.
