How to fix the stuttering on Gainward RTX 5070 Ti in Sims 5?
It was a night and day difference! The second I switched the driver from power-save to high performance, those tiny hitches while editing houses just vanished. The new architecture on the RTX 5070 Ti aggressively downclocks during low loads, but the driver latency meant the clock couldn't ramp up fast enough when the load spiked, leaving my 1% lows swinging wildly between 35-50 FPS. I tried forcing a higher resolution to keep the load up, but that just doubled my power consumption without really fixing the feel—a pretty inefficient way to troubleshoot. I eventually locked the power plan to 'Maximum Performance' and enabled low-latency mode in the panel. Frame times tightened up from 18-38ms to a consistent 12-16ms, and the input lag is gone. My idle temps did jump by 8°C at first, but I fixed that by tweaking the fan stop threshold. Core temps are now stable at 60°C - 68°C, and frame generation is consistently hitting 5.1-6.4ms.
