Stabilizing Sapphire RX 7650 GRE clocks in Horizon Online

Seeing my 1% lows jump from 38 FPS to 55 FPS was an absolute rush! The default clock scheduling on the Sapphire RX 7650 GRE is way too aggressive when rendering dense foliage, causing the core to bounce between 2000-2400 MHz, which created this annoying jitter. I first tried enabling Radeon Boost in the AMD driver, but while the peak FPS went up by 3, the minimums became even more erratic—just a complete disaster. I used Overdrive to lock the core clock at 2250 MHz and tweaked the voltage from 1.05V to 1.1V. RTSS showed the frame time graph flatten out to a consistent 14-17 ms, making combat feel way smoother. I did have one driver crash right after the lock, but backing off the memory clock by 50 MHz solved it. The GPU stays cool between 64-70°C. After a few hours of testing, the minimum frame stability is night and day compared to stock settings.
