How to fix VRAM stuttering in Zenless Zone Zero on RTX 5080?
Right in the middle of a fast combo, the screen would just hitch for a split second, and in an action game, that totally ruins the rhythm. Checking the backend, the Manli RTX 5080's GDDR7 bandwidth was hitting 12-18ms scheduling delays with 4K textures, causing frame times to jump erratically between 8-25ms. I tried the 'Prefer Maximum Performance' driver setting, but it just boosted the clock without touching the latency—completely useless for this specific issue. I used DDU to wipe 8.2GB of old shader cache and toggled the power management mode again. In RTSS, the frame time graph finally flattened out to 7-11ms, and the combat became buttery smooth. The only downside was that the first load after clearing the cache took an extra 30 seconds, but it was fine after the second launch. VRAM usage is stable at 11.4-13.1GB with temps at 56-62℃. 3DMark confirmed the fix, and the card stays cool at 56-62℃.
