Radeon VII Gaming on Windows 10 TB2

I use the Radeon VII on Windows 10 in a Razer Core X enclosure through TB2 adpater. I got it running under windows and mac. The problem is that the Radeon VII produces 30 to 40 fps max in for example Destiny 2 (Full HD). The same amount I can get if I am using my dGPU. And no, it is using the eGPU at that moment. Radeon VII max temperature at that time about 87 degrees Celsius under full load.
I don't know what to do... guess I have to give up on accelerating the graphics performance of my iMac. That is a reference what the card should be able to do, keep in mind though that u have approximately 20% or more performance loss out of the box when using the card as an eGPU instead of the use in a legit gaming rig (and I use TB2 because I simply have no TB3 available on my iMac): https://www.guru3d.com/articles-pages/amd-radeon-vii-16-gb-review,18.html
Nevertheless the performance I get now is more than half the performance it should achieve.

Any ideas folks?

@speedyconzales,
the limited bandwidth of TB2 can be a problem in some games, but doesn't have to be. Some games perform almost equal in TB2 like TB3.
Unfortunately some games perform quite bad with Radeon VII as you can in this comparison.

I don't have Destiny 2, could you post some other benchmarks in order to compare? Perhaps a couple of games of those games.?

I tried some world of tanks now. The results are on a Full HD 144hz monitor: average of about 100 fps with the Radeon VII. But showing a weird pattern fps going from 110 to 70 and up again repeatedly, even if there is no input at all (just sitting at one place and waiting). The dedicated GPU of my iMac achieves about 55 fps on Full HD but much more stable. 50 to 60 fps most of the time, not showing that weird pattern of fps going down and up again.

Then I investigated this issue: The weird pattern was caused by the AMD Radeon WattMan window which I had displayed on the internal monitor. As soon as I closed the window or switched to external monitor only, the fps were much more stable. But still only about average 115 fps on Full HD. Despite the fact that world of tanks is not my type of game, that is no overwhelming performance (including all the bugs and weird dependencies). Sadly my experience with other games was even worse. Guild Wars 2, which I play a lot, managed to run unplayable with the eGPU plugged in. With the dGPU I get more fps than with the eGPU. Why is that? I tried out Fortnite, a game I also do not play, but for some reason I wanted to test it out. There I got 140+ fps on Full HD. Whereas Destiny 2 seems to take no advantage of the eGPU. I do not have other games as benchmarks at the moment. But I did the luxmark benchmark on macOS and windows to verify a functioning graphics card and at that point it seemed very well functioning.

My question now is, which is the most powerful NVIDIA card which is "supported" on both OS (mac and windows)? With supported I do not mean officially supported by Apple, but you can get it running somehow. As I first checked, it seemed that the RTX cards are not supported at all under macOS. Therefore I decided to go with the competitor, the Radeon VII. Especially as I saw a lot of benchmarks   
which indicated that it could achieve similar results like the RTX 2080. But now... I am very disappointed by the results. Especially when running in an eGPU enclosure, I think that NVIDIA is still the way to go (after all that information and personal experience of the last couple days). But I do not wanna buy a card that can only run on windows. Then I would rather save my money and buy a full gaming rig to get the last 20% performance of the graphics card, too.

None of this makes any sense. The Vega VII is a Vega 64 with less stream processors, higher clocks and 2 more stacks of HBM2. 

Try running the HBM2 at 600Mhz instead of 1Ghz. That's the only thing I can think that's causing the weirdness. Maybe 1TB bandwidth is too much.

The Titan V CEO Edition 32GB should have the same issues in eGPU mode.

I didn't experience any lag with Division 2:

Did you try disabling the dGPU completely? What are your switchable graphics settings?

TB2 is often the bottleneck, especially in CPU bound games.

@speedyconzales
The most powerful nVidia card supported by Windows and MacOSX Mojave is GeForce GTX Titan Black


But consider that it's 5 years old and it performs in the league of a GTX1060 or RX580, even though it has some interesting features like FP64 performance and better chip quality.


The next best choice is either (A GTX780Ti 6GB doesn't exist, that's the Titan Black):
-GTX 780 Ti 3GB
-GTX 780 6GB

I will go with this statement. Especially Guild Wars 2 is a heavy CPU game and for some reason, if I use the eGPU, CPU usage is only about 20%. When I am playing with dGPU CPU usage is much higher, as you would expect. I do not know what is causing this. I tried disabling dGPU completely, therefore in the AMD settings application there is no tab for switchable graphics anymore. I will go with the TB2 causing this major problems.

Typically DirectX 9 games are so old they get easily hundreds of FPS in eGPU setups, too.

If you want (and I can get the game), I can test Guild Wars 2, too, on either a TB2 and TB3 system. I don't have a Radeon VII anymore so I can test it with GTX 1080 Ti, Radeon RX580 or GTX Titan Black. I do expect easily > 100 FPS on every system/gpu combination. I would even bet it's far beyond 200 FPS on TB3/GTX1080Ti. Tell me your exact resolution and preset of the game.
I can try this DX9DX12 wrapper, too. It's intriguing.

EDIT: On which OS are you playing Guild Wars 2?
