How to fix resource scheduling on Manli Snow Fox RTX 5080 OC?
When hitting those ultra-high res textures in Starport, my Manli Snow Fox RTX 5080's memory clock was bouncing wildly between 2600 MHz and 2800 MHz. It was a nightmare, with FPS tanking from 120 down to 75 instantly. I honestly started questioning the GDDR7 scheduling logic. At first, I tried enabling Enhanced Sync in the driver, but that just bloated my input lag to 25ms without fixing a single stutter. I was totally lost. Eventually, I used MSI Afterburner to force the core clock at 2550 MHz. Checking HWiNFO, the core temps sat steady between 66°C - 72°C, and the frame time finally converged from 12.5ms down to 8.4ms. I initially thought I was hitting a power limit, but the power draw was only 310W; the real culprit was the lag during frequency switching. After a second attempt undervolting the core to 1.02V, the card finally locked into a stable high-frequency state, and that snappy response came right back. After running a stress test, the efficiency peaked at 320W, and those annoying micro-stutters vanished completely. Frame times are now rock steady at 5.1-6.4ms, though it took way too much tinkering to get here.
