How to fix IO conflicts on Onda 9D4-DVH in Once Human?
The compatibility on this board is a total joke. Every time a large building loaded, the screen would just freeze for half a second. The IO scheduling on the Onda 9D4-DVH struggles with the asynchronous load requests of modern games, causing bus conflicts that hang the CPU. I tried swapping in higher-frequency RAM, but the board didn't support it, which was a complete waste of my time. I eventually went into Device Manager and turned off 'PCI Express Link State Power Management' and updated the chipset drivers. In my tests, the random hitches dropped from 10 times an hour to almost zero, and the game feels much more responsive. I noticed my idle power draw went up by about 5W after this, but I fixed that by tweaking the CPU C-States. Board temps stayed at 50-56℃. I exported the BIOS settings, and now the controls feel snappy and instant.
