Dealing with disk scheduling lag on Onda B760ITX-B4
Every time a massive explosion or destruction effect happens on screen, the game just freezes for about 0.3 seconds, and that inconsistency is honestly anxiety-inducing. I found that the bus bandwidth on the Onda B760ITX-B4 was struggling with heavy random R/W operations, with I/O wait times peaking at 150-220ms. I tried enabling Windows Game Mode, but while the general OS felt a bit faster, the physics stuttering remained exactly the same—it felt like I was chasing my tail. I eventually used a process scheduling tool to set the game's disk priority to 'Realtime' and killed about 8 useless Windows background services. Checking Resource Monitor, the disk active time dropped from 98% to around 70%, and the physics engine finally started breathing. I actually broke my network driver while disabling services, and I had to manually restart the network adapter service to get back online. The motherboard is running at 45-55℃ with CPU peaks at 78℃. After comparing the performance curves, I saw a 25% boost in I/O efficiency, and the input lag is finally gone.
