Solving GDDR7 memory stutters on Manli RTX 5090 D in Where Winds Meet
Whenever I'm speeding across the map and whip the camera around, the FPS jumps erratically between 110 and 150. It completely kills the immersion. Even with the massive bandwidth of the GDDR7 memory on the Manli RTX 5090 D, the memory controller refresh cycles were swinging between 12-28ms at 4K Ultra, creating uneven data latency. I tried enabling Windows Game Mode, but that did absolutely nothing for the hardware-level bandwidth spikes. I eventually went into the driver panel and manually locked the memory clock to 2100MHz, then updated to the latest Game Ready driver. RTSS showed the frame time variance shrink from a wild 15-30ms down to a stable 18-22ms. The core temp climbed from 65℃ to 72℃ after locking the clocks, so I had to bump the fan curve to compensate. Now VRAM temps sit at 78-84℃ and the core is at 68-74℃. The jumping is gone, and RAM temps are steady at 58-63℃. It's finally the beast I paid for.
