How to stop CPU frequency fluctuations in Destiny 2?
Honestly, after tweaking the voltage offset, those annoying drops in raid combat just vanished. It's a total game-changer. Before this, the DeepCool AK620 ARGB couldn't keep up with the physics calculations, and my CPU was hovering between 82-88℃, causing the clock speed to bounce between 4.2GHz and 4.8GHz. I tried a raw overclock in the BIOS first, but the temp hit 98℃ and the PC shut down—that was a wake-up call. I switched to an undervolting strategy, setting a -0.05V offset and a stepped fan curve. In RTSS, my frame times dropped from 12-22ms to a tight 8-11ms. I actually pushed the voltage too low at first and got a blue screen immediately upon launching the game, so I backed it off to -0.04V for the sweet spot. CPU temps are now 68-74℃. Performance panels confirm frame times are rock steady at 5.1-6.4ms.
