This is the first game I've run where system memory is completely consumed. My hardware is as follows:
iMac 4k 2015 - 21.5" (iGPU only)
i5-5675R @ 3.10 GHz
8 GB RAM
Aorus Gaming Box 1070 via TB3 > TB2 adapter
Windows 10.0.17134
Like I said above, system RAM is completely consumed when running this game. I feel my results would have been much better with 16 GB.
VRAM usage ranges from 2.0 - 4.5 GB. It seems to be completely dependent on the quality preset, resolution doesn't make a difference. All testing was done on the iMac internal display using the new built-in W10 Graphics Switching (no Optimus support with my iGPU unfortunately).

This is only the game that I couldn’t understand, my Rtx 2080ti performs overall worse than 1070 maxq dgpu on my host device, unlike other games. I hope it’s just driver optimization matter. FHD and 4K benchmarks on Ultra (auto hardware detection)

I have the same issue with Forza 4.
The mobile 1050ti maxq performs better than the 1080ti.
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@itsage, Forza Horizon 4 demo is a free 28GB download from MS store. Did you want to do some TB3 benchmarks? Desktop performance across different dGPUs, resolutions and qualities, useful for comparison, has been tested by several sites:

M.2 (NVMe SSD port) eGPU performance using ADT-Link R43SG
Here's a morsel of my tinkerings awaiting some hardware for release. This is using the system's M.2 NMVe SSD port rather than Thunderbolt 3. Performance is spectacular.

It may be interesting, that with 1440p the result is 65-67 FPS.
This is good evidence that this game is limited by the TB3 bandwidth. Further, on a TB2->TB3 adapter this same GTX1080Ti only makes 44 FPS on 1440p.

Finally got around to installing this demo and benchmarking. My interest got sparked over the Radeon VII testing in Bootcamp posts in which the game is showing the limitation of TB3. Here's my info and results (not so sure why my plots are much more spread out than the ones already posted here):
2014 Mac mini , Core i5-4278U, Dual Core @ 2.6GHz, Turbo Boost to 3.1GHz, 16 GB RAM, 1 TB HDD
ASUS XG Station Pro w/Apple's TB2->TB3 adapter
EVGA 1070 Ti Gamers (Blower)
Benchmark on FHD and Ultra preset with Vertical Sync turned off.
39 FPS running from the mini's HDMI port to external display:
30 FPS running from eGPU's HDMI port to external display:
I didn't know that there would be this much of a difference between the internal and external HDMI. Does anybody know that this is always the case with Macs in general or all headless types of PC's?
