FPS on Fortnite with RX 5700 XT

I have a MBP with an i9-9880H and a RX 5700 XT hooked up to an external 1440p monitor in Windows 10 (Bootcamp). I've been trying to test out performance when running Fortnite (as it's a bit more CPU intensive from what I understand) and I'm getting mixed results.

On 1080p with low I get 176 FPS and epic I get 103 FPS.

On 1440p with low I get 167 FPS and epic I get 83 FPS.

I monitor the CPU usage (across all cores) and none of them ever go above 70% individually and unless I'm running on epic 1440p, the GPU load is quite low. For example, when I'm running on competitive settings the FPS doesn't differ between 1080p and 1440p. The GPU and CPU will sit at a fairly low level (around 50-60%) and output around 140 FPS on average. Am I correct in assuming I'm hitting a TB3 bottleneck and that's why it's not putting out more FPS?

It's optimization "features", low power mode, etc.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Do you have Multithreaded Rendering turned ON in Fortnite’s in-game settings?

I found that force the CPU clock at higher frequency gives me better performance in some CPU-demanding games like hell let loose. Otherwise it would sometimes sit on <3.0 GHz to save power.
