How to fix resource scheduling on Sapphire PURE Polar RX 9070 XT?
Whenever I trigger high-frequency elemental reactions, the frame rate suddenly tanks from 60 FPS down to 42 FPS, which is a total nightmare for anyone trying to play technically. I noticed the core voltage on my Sapphire PURE Polar RX 9070 XT was dipping around 1.0V, causing the clock speeds to bounce wildly between 2100MHz and 2500MHz. I initially tried enabling FSR, which bumped the frames back up by about 15 FPS, but the jagged edges were just hideous and completely unacceptable. I eventually dove into the driver settings and applied a manual core voltage offset of +50mV, while locking the minimum frequency at 1900MHz to kill that scheduling lag. In AIDA64, the peak core temp climbed from 62°C to 68°C, but the stuttering completely vanished. I did hit a snag where the game crashed ten minutes in after the first voltage bump, but stabilizing the max clock by dropping it 50MHz fixed it. Now, VRAM temps sit steady at 60-66°C and the frame times are rock steady at 5.1-6.4ms. It's a bit of a power trade-off, but the stability is worth it.
