Razer Blade 15 + Core X Chroma + GTX 1080ti Performance Issues

I currently have a new mid 2019 Blade 15 with 240hz Display and RTX 2070 and have recently purchased a Razer Core X Chroma for my GTX 1080ti for a graphics boost when I am at home. I am experiencing heavy performance loss with this 1080ti in the Core X enclosure and I am not sure what the issue is other than the TB3 overheads, which I was told were around 10%. Currently this is performing noticeable worse than my built in dGPU 2070. I have tried it on just two games at present. Battlefield V and Control. 2070 dGPU – Control – 60fps BFV – 70fps 1080ti Razer Core X – Control – 40fps BFV – 50fps Both of these were on the exact same settings on an external 1440p monitor wither plugged into the Core X via a display port cable or into the Blade 15 2070 via a mini display port cable. As you can see the 1080ti settings are a lot worse than the built in 2070 dGPU and I want to know if I have missed something or need to change any settings. I have tried multiple things including –

• Updating all drivers
• Disabling my dGPU via device manager
• Installing Razer Switch App to disabled the dGPU
• Tried with and without peripherals plugged into the laptop and / or Core X
• Uninstalling / reinstalling / updating drivers, thunderbolt settings, the Core X itself, razer programs, etc.

I have ran all games with monitoring software and the CPU have never maxed out, and has only ever seen 70-80% load max and was usually at 60-70%. The GPU on both the 2070 and 1080ti in the core X were both maxed out at 90-100% most of the time. Which leads me to believe that my laptop CPU is not a bottleneck. Could you please let me know if this is acceptable performance for the Core X considering the GPU that is installed into it.
