eGPU Incompatibility with Halo

Whenever I attempt to play halo with my eGPU (external graphics card), the game runs terribly, yet the GPU utilization says 100%. The fans on the card don’t spin and I get around 30-40 fps no matter how much I tweak with the settings. The card is a VEGA 64 and the eGPU case is the razer core X. I can confirm that the card works with other games as well. I’m at a loss here, but I think this is an issue that 343 is aware of. Just want to make sure this gets patched before the game releases.
