Is the RTX 5060 Ti 16G VRAM bandwidth causing stutters in Witcher 3?
Walking through Novigrad, I felt these micro-stutters every few seconds—that lack of responsiveness is a nightmare during combat. Monitoring the backend, I saw the RTX 5060 Ti 16G VRAM bandwidth fluctuating by 12-18% with Ray Tracing on, causing frame times to jump between 16ms and 32ms. I tried dropping RT from 'Ultra' to 'High', but I only gained 5 FPS and the hitching stayed; it was a useless compromise. I went into the NVIDIA Control Panel, set Power Management to 'Prefer Maximum Performance', and manually overclocked the VRAM by 100MHz. RivaTuner finally showed a smooth 14-18ms frame time. I actually pushed the clock too far at first and got some nasty artifacts on screen, so I had to dial it back by 50MHz to get it stable. Now the GPU is at 65-72℃ and VRAM is 78-84℃. The response time is finally back to normal.
