Why does Kingdom Come: Deliverance crash in towns on Maxsun B650M WIFI?

Just as I was about to sneak up on my target, the game crashed to desktop, making all my stealth efforts pointless. I tried setting virtual memory to half of the remaining disk space, but this maxed out disk I/O and increased crash frequency. I used GamePP Resource Scheduler to set the game process to Realtime priority and optimized the minimum energy state. AIDA64 showed frequency fluctuation dropped to 0.1GHz, and response time stabilized at 40-60ms per RTSS.
