I just tried it out and unfortunately it didn't work for my use case. Only certain applications are currently allowed to get accelerated by the eGPU - like Photoshop. I wanted to accelerate WebGL, but it was impossible to make it work. Chrome(ium)/Firefox/Safari, nothing worked. I tried a lot and the browsers showed the eGPU as the card to be used, but it was still the Intel Iris. When someone has any pointers what I made have done wrong, I would be super grateful, but my research was, that it just doesn't work yet.
