How do I stop texture flickering in Tales of Justice Academy with GW3500 512GB?

While exploring the ancient city, I saw textures vanish and reappear, which was incredibly annoying. I tried clearing temp files, but it worsened disk fragmentation and read latency. I then used GamePP Resource Scheduler to set the game process priority to highest and limited background antivirus scanning. AIDA64 storage tests showed sustained write speed stable above 3500MB/s. Texture loading latency dropped from 120ms to 15ms. The visual glitches are gone, and this fix restored the smoothness I expected from the open world.
