My Gainward RTX 5070 Ti Snow Step OC 2.0 is throttling and dropping frames under high load in Sword and Fairy 7 (Upgrade). Can I fix this with process priority?

This card turns into a literal space heater under load. Core temps were spiking to 82°C - 87°C, causing the clock to dive from 2.6 GHz to 1.9 GHz—absolutely ridiculous performance loss. I tried cranking the fans in the driver, but it just sounded like a jet engine taking off in my room while the temps barely budged. Total waste of effort. I eventually dove into the overclocking tools and set a negative voltage offset of -0.05V. In the logs, I saw the peak power draw drop from 280W to 240W. It wasn't a smooth ride; the system rebooted twice when I first tried lowering the voltage until I tweaked the load-line calibration. Now, the GPU stays between 72°C - 78°C and the frame variance is within +/- 3 FPS. It's a tedious manual process, but it stopped the embarrassing power-drop throttling. I no longer feel like I'm burning my hand when touching the top of the case. My logs show fans stable at 1400-1600 RPM, though the card's stock cooler is clearly inadequate.
