How to fix VRAM spikes on Zotac RTX 2060 Super in GTA VI?
Tearing through the neon-lit streets was a nightmare; the frame rate was all over the place, making the controls feel sluggish and unresponsive. The 8GB VRAM on my Zotac RTX 2060 Super is honestly struggling with the texture load of this new engine, with VRAM usage jumping wildly between 7.8GB - 8.2GB, forcing the system to lean on the agonizingly slow virtual memory. I initially tried forcing 'Prefer Maximum Performance' in the NVIDIA Control Panel, but that was a mistake—it didn't stop the lag and just pushed my core temps from 68℃ up to 82℃. I was totally lost for a bit. Eventually, I dove into the Advanced System Settings and manually locked the page file to a non-symmetric range of 32GB - 48GB and disabled Windows Fast Startup to clear out the junk cache. Checking GPU-Z, the memory clock finally settled from an unstable 14000MHz down to a rock-steady 13850-13900MHz, and frame times dropped from a chaotic 22-21ms range to a smooth 16-21ms. I actually hit a Blue Screen of Death (BSOD) the first time I messed with the page file, and it only stabilized once I moved the paging file to my high-speed NVMe SSD partition. Now, core temps hover around 72-76℃ with fans spinning at 1800-2100 RPM. Resource Monitor shows a much smoother allocation curve, and the 16-21ms frame time is finally consistent, though the 8GB limit still feels like a bottleneck in some spots.
