Finally, I’ve completed my primary goal with eGPU.

Tonight my Vive Pro came, and the iMac+2080 ti drove it beautifully. 
Only played few min with BeatSaber. Coming from PSVR, the controllers are heavier, but tracking is much tighter.
I didn’t notice any lags using eGPU even when I was on expert level (e+ is bit much for me yet).

The setup was easy. I am using the 2080’s USB-C port, adaptor to get DP, 15’ DP cable and another adaptor into mini-DP.
The Vive doesn’t seem to care that it was hooked up to eGPU at all. The latency monitor on the SteamVR didn’t go over 11ms (90Hz) during game play.

Going to try DCS next and see how it plays.

I will have extenders coming on Friday, once they arrive, I will try it in the another room with 30’ of cables.

Sounds very impressive! good job.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
