Thanks @jackeyjoe

3DMark's Time Spy, basic version is free. With it you'd need to manually set your display's resolutions before running it. We don't expect 4k resolutions to work too well on the internal screen (via Optimus over x2 lanes), but switching to 1080p and 1440p might show interesting results. I'd be curious to compare internal vs external at each resolution if you have the time to run the test 6 times.

Also, I'd be very interested to hear how Battlefield 1 performs on your rig if you can show up. It is currently a free-to-play weekend. It's one of the most intense 3D games I know of and runs in either DX11 or DX12.
Free Trial Weekend

From how I'm reading your screenshot, I'm fairly sure that shows the Thunderbolt cable (called "PCI Express x4 Bus #9") between the motherboard and your USB hub. The ethernet and other peripherals then connect to it, but I don't think it's relieving the bandwidth yet as expected. Do you see any change in HWinfo when you unplug/plug the USB-B cable? Does Windows indicate new hardware?

When you do your testing, try to remove any USB devices or even temporarily disable that USB hub entirely from the Device Manager.

XG Station 2: Switched USB-B cable: USB controller vs Thunderbolt controller

 

Definitely runs off a USB when connected, and switches to the thunderbolt controller when not. All peripherals disconnect for a few seconds when you unplug the USB type B cable, and show up elsewhere in HWInfo after restarting it. Is that not enough proof that it's being routed outside of the thunderbolt connection?

 

I'm having driver issues with the 3DMark bench, it seems to be running off my internal GPU's if my scores are to be interpreted correctly. I did a bench of Rise of the Tomb Raider at 1080p and 4k on both screens though:

4k internal: 29.55 FPS

4k external: 38.42 FPS

1080p internal: 56.45 FPS

1080p external: 67.83 FPS

 

This was DX12 everything maxed but FXAA instead of SSAA x4 and vsync off.  For my use case (4k external) this puts me 5-7 FPS behind what reviewers are getting online(some don't state settings annoyingly), which is acceptable losses for me. I'll go through BF1 ASAP too, but it looks like running through the internal display leads to a hell of a performance drop.

Thanks @jackeyjoe

The only hwinfo I've seen (annotated here) seems to show the USB hub attached to the XG's Thunderbolt 3 Controller which is connected over the Thunderbolt 3 cable. The behavior you're describing suggests the hwinfo hierarchy should appear differently when the extra USB-B cable is added, which would make sense. I just don't see it in that screenshot you had provided. I'm guessing that shot was just taken without the extra USB cable.

 You can manually switch which GPU is used for 3Dmark using Nvidia Optimus. Here's showing the two ways to control this. Note: 3Dmark TimeSpy is extremely demanding so low FPS is to be expected with it.

For Tomb Raider, it looks like using the internal screen at 1080p resolution shows a 7% difference while the increased bandwidth of 4K resolution takes a more significant 23% hit. This seems sensible given the x2 lanes of PCI. At these maxed settings and their low FPS, both are losing just under 10 frames each second. For actual gaming on the internal screen, I'd recommend a lower resolution and settings that hover above 60 FPS, perhaps with an artificial frame limiter as @nando mentions in his OP. I suspect 1440p resolution would be comparable to the 1080p results if you compared those.

And thanks @nando, I'm looking forward to seeing the XG Station 2 listed in these Implementations. It's now been released in Australia and the Philipines, but not yet North America or Europe. I suspect it'll be one of the more interesting enclosures once it arrives.

This is my HWInfo64 screenshot when connected(has a keyboard, mouse, USB DAC and trackIR connected):

It is showing up under the USB controller, not through the thunderbolt connection. Obviously this changes when the USB port is disconnected. Does it make more sense now?

Yes, that's exactly what we were expecting. Didn't see it in the previous screenshot. Thanks!

All of the XG Station 2's USB traffic is routed away from Thunderbolt 3. Connecting a USB 3 hard disk with all your games would enable a very nice gaming dock setup and free up the limited internal storage within a laptop.

I live in Hong Kong. I bought XG2 with great hope to use it in my Macbook pro 13 late 2014. Of course, the XG 2 could be recgonised but the external GPU could not be recgonised under the Mac OS. No luck!

After Jackeyjoe's work, ASUS released the firmware some days ago. So, with the arrival of a TB3 notebook with Windows 10 a few days ago, I decided to try XG2 under a pure PC Windows 10 environment. My PC notebook is Vaio S11. It is available in Japan, but luckily my friend got it to me. I guess it is the cheapest TB3 PC notebook that I can get here to test the XG2. 

At first, I connected the XG2 station with the EVGA Nvidia 1050 (No Ti version). I installed the new Thunderbolt driver from Intel as instructed under another thread from Asus where Jackyjoe got the response there. No luck. The notebook recognised the XG2 but the external egpu was not recognised. I therefore downloaded the new firmware at that thread provided by ASUS and flashed the firmware of XG2.

Well, after flashing the firmware, I re-started the notebook, and connected the XG2. Oh, some strange things happened. The thunderbolt connection was ok, but the windows prompted that "The Thunderbolt Connection may not be working properly". When I clicked the thunderbolt icon, it still said that the external gpu was not supported. However, the icons of Nvidia Control Panel showed up. It proved that the 1050 card was recognised! So I run the Unigine and well, yes, the notebook recogised the 1050 card.

Here comes the screen shot.

And now, I plug the XG2 to my Macbook late 2014, with TB3-TB2 adaptor. I run the goalque's script. This time, the goalque script recognises the 1050 card. Of course, the Mac OS does not support Nvidia 10 series so it cannot be run in Mac OS. But it proves that after flashing the firmware, the GPU card in XG2 can finally be recognised under Mac OS 10.12. I shall find my Nvidia 980 later and test it under Mac OS again, and report the result in Mac OS side of this forum.

@jackeyjoe What kind of experience are you getting in BF1 or other games you've tested?
