How can I calibrate VRAM throughput for RDR2 on Gainward RTX 5070 Ti?
That suffocating feeling when the screen just freezes for a full second while riding into Saint Denis is a nightmare; the input lag becomes unbearable. Looking at the GamePP Hardware Sensor Page, my Gainward RTX 5070 Ti VRAM usage was fine at 8-11GB, but the memory controller load curve was spiking by 25-50ms, creating a massive data bottleneck. My first instinct was to enable 'Prefer Maximum Performance' in the Nvidia panel, but that actually increased the frequency of the stutters—just my luck. I eventually switched to the GamePP Resource Scheduler Panel, set the game's VRAM priority to 'Highest', and killed every background process with hardware acceleration.
