I'm getting major I/O blocking and frame drops in Manor Lords during city expansion on my Great Wall GW3300 512GB. Do I need to change disk priority?

I finally got it running! Even with only 512GB, some extreme optimization made it playable, which is actually a rush. The GW3300 512GB is just too small for massive city simulations; the system kept hitting a 0.8-1.5GB virtual memory deficit, causing the game to hard lock. I first tried tanking every single graphics setting to the absolute minimum, but the game looked like a mosaic and still crashed during saves, which was an incredibly frustrating experience. I then manually locked the page file to 16GB and tweaked the disk I/O priority weights in the registry. I saw the memory swap frequency drop from 110 times/sec to about 35-50 times/sec, and I can finally maintain 45 FPS. My boot time slowed down by about 2 seconds after the I/O tweak, but disabling 'Fast Startup' fixed that. Drive temps are 40-52℃, and the speed is steady at 3300MB/s. Frame gen is now stable at 5.1-6.4ms, though the drive is still a bottleneck.
