How to optimize power states on Onda A520-VH-W for gaming?
That feeling of instant teleportation was being ruined by these heavy stutters. Looking at the logs, my CPU clock was plummeting from 3.8GHz to 1.2-1.5GHz in about 0.2 seconds, causing the FPS to crater. I realized I'd set the C-State power saving too aggressively in the BIOS to save a bit of electricity, which created a massive wake-up delay—my obsession with efficiency was killing my performance. I went back in, disabled all deep sleep states, and raised the core voltage floor to 0.85V. Now, the clock speed is locked between 3.6-3.9GHz, and frame intervals have tightened from 16.8-24.2ms to 10.5-12.8ms. I tried increasing the virtual page file first, but that just caused a nightmare of disk read/write conflicts; moving the game to a high-performance NVMe drive finally killed the stutter. This board doesn't have many power phases, but once you kill the power-saving limits, it actually punches above its weight. Frame times are now stable at 10.5-12.8ms.
