Fixing Zotac RTX 5070 Ti performance spikes in DD2
The moment a dragon lands, I get these tiny hitches in the animation. It's a bit annoying, but honestly, seeing what this hardware can actually do gets me hyped. The Zotac RTX 5070 Ti was struggling with complex physics, and because the OC core voltage offset was slightly off, the clock was bouncing between 2500 MHz - 2700 MHz. I tried turning on Hardware-Accelerated GPU Scheduling, but it only gave me about 3 extra FPS and the hitching remained. I realized I had to go deeper. I used a voltage-frequency curve tool to lock the core at 2610 MHz and bumped the voltage to 1.08V. In RTSS, the frame generation time tightened from 14ms - 28ms to a smooth 9ms - 13ms. The jumps are completely gone. The card initially spiked to 82°C after the lock, so I had to crank the fans to 85% to keep it between 68°C - 74°C. Now it's running like a dream. The performance panel confirms the sync mode is active, and frame times are steady at 5.1ms - 6.4ms.
