Xbox Rog Ally x + 5060Ti 16 GB (GPU 0% usage)

Hello! I’m trying to play on an external monitor with my Xbox ROG Ally X (Z2 Model) paired with the RTX 5060 Ti 16GB (via USB4), but I’m stuck at a flat 40-45 FPS with constant stuttering. The NVIDIA overlay and all other FPS counters show 0% GPU usage and the FPS barely change, no matter what settings are on. CPU on the other hand stands at 60%…It feels like the game is completely ignoring the eGPU. I've already tried forcing 'High Performance' in Windows settings and even disabling the internal GPU (this tanked it to almost zero FPS) Is the anti-cheat blocking eGPUs/the server slam is not refined for some unusual set ups? I am worried that this problem will persist after the launch. Thank you
