How to fix VRAM bandwidth spikes on Zotac RTX 2060 Super?
The moment I'd destroy a bunch of voxel blocks, the smooth gameplay would just hitch, which was honestly baffling. I dug into the logs and found the Zotac RTX 2060 Super's VRAM bandwidth was hitting a wall with dynamic vertices, causing resource scheduling delays between 16-24ms. I first tried dropping texture quality to Medium; it gave me about 8 more FPS, but the visuals looked washed out and blurry, which was a total letdown. Then I dove into the NVIDIA Control Panel, set Power Management Mode to 'Prefer maximum performance', and manually locked the memory clock at 14Gbps. Checking RTSS, the frame times collapsed from a wild 20-38ms swing down to a rock steady 11-15ms. I actually wasted an hour trying to increase the page file size first, but that just made the whole system feel sluggish until I killed all my background apps. GPU temps stayed around 68-74℃ with fans humming at 1800 RPM. Ran a 3DMark storage benchmark and the throughput is back to peak. Everything is saved and running smooth.
