Why is my Ryzen 9 9950X3D dropping frames in Witcher 3 Next-Gen?
Walking through the streets of Novigrad and seeing my FPS tank from 140 down to 60 is just pathetic for this hardware. The 3D V-Cache on the 9950X3D was having scheduling conflicts between the CCDs during heavy NPC loads, causing data throughput to swing between 40GB/s - 55GB/s. I tried lowering the crowd density, which gained me about 15 FPS, but the city felt like a ghost town—absolutely not an option. I went into the BIOS, changed the Load Line Calibration to L3 mode, and used a scheduling tool to force the game process onto the cores with the 3D cache. AIDA64 showed my memory latency dropping from 68ns to 58ns, and the city stutters mostly vanished. I did have a random reboot when I first bound the cores, but adjusting the voltage offset from +0.02V to +0.01V stabilized everything. CPU temps are around 72℃ - 78℃ with fans at 2200 RPM. I saved this config to a backup, and the input response is finally snappy again.
