I've seen GPU-Z show the eGPU as both PCI-E x4 1.1 and 3.0 and I'm not getting the benchmark scores I expect, although I am using my laptop display.

Any help boosting performance would be appreciated

@arun_langley, I believe the Yoga 730 15" with the dGPU only has a 2 PCIe lane connection to the Thunderbolt 3 port. For best performance you should connect the eGPU to an external monitor.

@itsage, so it's just a bandwidth issue? is there anything I can do to improve performance in the meantime? (still saving for a monitor)

cheers

@arun_langley, Have you tried disabling the GTX 1050 in Device Manager so that the eGPU can work with iGPU? Maybe it provides a bit better performance due to better cooling.

@itsage, Yes, after your advice on whether to use the dGPU for PhysX or not I have kept the 1050 disabled for better thermals. If 2 lane TB3 implies half the bandwidth of 4 lane then I can understand my benchmark scores and will just have to get an external monitor. I was hoping to take advantage of my UHD laptop display for high-res stuff and then get a 144hz FHD display for shooters but maybe I should save up more and get a 1440p 144hz monitor to cover both.
