How to fix VRAM throughput issues on Onda 9D4-DVH?
When managing a massive colony, the VRAM scheduling on the Onda 9D4-DVH goes haywire, causing noticeable screen tearing whenever I zoom out. HWiNFO showed VRAM usage spiking wildly between 3.2GB - 3.8GB, which made the whole experience feel sluggish. I first tried dropping the texture quality, but the game just looked like mud and the stutters stayed—it was honestly infuriating. I eventually dug into the system settings and manually locked the virtual memory to a fixed 16GB - 20GB range. After that, I saw the frame times shrink from a choppy 22-35ms down to a much tighter 14-18ms. Interestingly, the page file change didn't do anything until I rebooted and disabled Windows Fast Startup; only then did the swapping frequency actually drop. During testing, the GPU core stayed between 66℃ - 72℃ with fans humming at 1200 - 1500 RPM. Comparing the bus bandwidth under load confirmed the data path was finally optimized. Even during the heavy blizzard scenes, the tearing is gone and frame times are rock steady at 14-18ms, though the 9D4-DVH still struggles with ultra-wide resolutions.
