How to stop the RTX 5070 Ti from throttling in Horizon Zero Dawn?
Whenever I fight a massive machine, my frame rate dives from 90 FPS to 35 FPS, and it's honestly infuriating. The Gainward RTX 5070 Ti spikes over 280W during heavy rendering, triggering a motherboard-level thermal protection throttle that drops the clock from 2.6 GHz to 1.8 GHz—a total nightmare. I tried Max Performance mode in the drivers, but the fans just screamed while the core stayed at 88℃, which felt completely futile. I switched to an Offset voltage mode, setting a -0.04V undervolt and capping the power limit at 250W. In CPU-Z stress tests, the clock fluctuation narrowed to 0.1 MHz, and temps dropped from 92℃ to 78-82℃. I lost about 2% in single-core raw performance, but in-game, the lack of massive drops makes it feel way smoother. GPU temps now sit at 72-78℃. Used the BIOS export tool to back up the voltage profile so I don't have to do this again.
