Macbook Pro 13" 2015 + RX 570 + Razer Core X Underwhelming Performance with internal display

Hello, first time eGPU user here. After trying to decide whether it's a good idea to build an eGPU setup for my Macbook Pro 13" 2015 I finally pulled the trigger and bought a Razer Core X with RX 570 as my graphics card of choice. Here's the complete detail of my setup.

13" Macbook Pro 2015
Razer Core X enclosure
HIS RX 570 4GB
TB3>TB2 Adaptor
Internal display via 2.0 m Thunderbolt 2 cable

Now, I haven't got my hands on a display monitor since I thought that the performance drop wasn't going to be significant compared to having the GPU plugged to an external display. But to my surprise, playing GTA V on Very High Settings at 1080p only yields to 26-35 fps, meanwhile lowering to Normal doesnt signficantly improve performance, but I noticed by lowering resolution to 1366x768 I can play at 30-40 fps, and even then its still not enough for a mid spec Graphics card.

Is connecting my egpu to an external display the absolute answer for performance gain? And if so will it significantly improve it. Any advice is much appreciated.

For further reference here's my benchmark results, with RX 570 @ 1400 MHz

I noticed that Macbook pro 13 2015, don't have a quad core processor option to buy, only dual core. Perhaps the low fps is caused by processor "i think". Because GTA V is a CPU Bound game and it could be the bottleneck of the RX 570.

@mr-ribeiro, true, it is only a dual core (4 thread) processor, and I was going to dismiss it on that. But then I saw this egpu benchmark on a 2013 Macbook Air (also a dual core) having no problem running GTA V at 40-60 fps 1080p. Maybe running on an external display is that significant for performance?

@matthew_nainggolan, have you tried setting your graphics options to "use high performance gpu" in windows? 

This is just a random screen grab of the feature, you should have RX570 under "high performance" option.

@eightarmedpet, yes I made sure it was in high performance and the RX 570 does run. Otherwise, the intel iris 6100 could barely run GTA V on 800x600. 

Maybe it's the best idea to upgrade to an i7 powered laptop with Thunderbolt 3 support.
