Why does my Vastarmor RX 9060 XT drop FPS in Kai no Kiseki?
Walking through the busy city streets, my frame rate would randomly tank from 120 FPS to 45 FPS, and that kind of jarring hitching completely kills the game's flow. The Vastarmor Radeon RX 9060 XT 16GB OC was aggressively downclocking to 800MHz during low-load scenarios, which created a bottleneck in the rendering pipeline. I started by enabling 'Ultimate Performance' in Windows, but while the CPU felt snappier, the GPU clock was still jumping all over the place—proving it was a GPU power management issue. I went into the AMD Adrenalin software, manually set the minimum frequency to 1500MHz, and bumped the power limit by 10%. GPU-Z now shows the core clock staying stable between 2100-2300MHz without any sudden crashes. My idle power draw jumped from 15W to 45W at first, so I had to rewrite my fan curve to keep the heat in check. Core temps are now 62℃ - 68℃ and VRAM is at 75℃ - 82℃. After recording three different combat scenes, the drops are totally gone, and memory temps are steady at 58℃ - 63℃.
