How to fix VRAM scheduling lag on Gainward RTX 5070 Ti?
The moment my frame rate tanked from 110 FPS down to 45 FPS, I knew the VRAM scheduling was hitting a wall; the stuttering was incredibly jarring when operating the heavy machinery. Digging into the data, the GDDR7 bandwidth on the Gainward RTX 5070 Ti was hitting 15-22ms of command latency while processing complex vegetation shaders. I tried setting the driver to 'Prefer Maximum Performance', but that was just a band-aid—the latency didn't budge. I realized it was a cache pile-up issue, so I used DDU to wipe 6.4GB of old shader cache and switched the power management mode to high performance in the control panel. In my frametime monitor, the variance dropped from 14-32ms down to a tight 9-14ms. Just a warning: the first launch after clearing the cache took an extra 40 seconds to load, but it's been rock steady since the second boot. VRAM usage is now hovering between 10.2-11.8GB with core temps at 58-64℃. Ran a 3DMark stress test and everything is finally holding up.
