Razer Core X Chroma bandwidth dips during games/under load

Hey yall,

I've been having a good time with my Razer Core X Chroma on Bootcamp (using a MacBook Pro 15", Mid 2019), but I have been encountering one consistent hurdle I cannot overcome: Why does my bandwidth drop while playing games/under load? I'm also using an EVGA GeForce GTX 1080 FTW.

I've tried a few different things to mitigate the bandwidth hit, including:

  • Unplugging all peripherals from the enclosure (only leaving the power, Thunderbolt 3 cable, and DisplayPort cable to my monitor)
  • Updating the Thunderbolt 3 drivers and PCIe controllers via this guide
  • Closing as many background tasks as possible
  • Disabled my dGPU in Device Manager (Radeon RX Vega 20)

Is there anything I can do to reduce the bandwidth hit I receive, or is that just a result of rendering the workload? I've also taken some screenshots from GPU-Z and CUDA-Z, I hope they help.

I did want to thank yall for being an awesome community and helping me work out so many of the problems I've had, and I wouldn't have made it this far without the help of yall contributing to this excellent website!

@camouflaged_cow, bandwidth is measured by sending data to or from the GPU. If the game is sending data to the card, then the benchmark cannot send as much data.
