Cosmos ready for industry usage or not

@VibrantNebula the Ryzen 2600X need to be a bit better than the i5-9600 so will see how will behave, but at first we will test the tethered solution to know if the Cosmos is enough for our needs. In any case I can easily upgrade up to a Ryzen 9 3950X that is past any Intel CPU, not sure if the wireless adapter require some Intel specific hw encoding feature. 

I ran with an overclocked 2600 to start with (on the Vive Pro with wireless) and managed to get it working relatively well. Suggest you make the following changes:-

1) Disable hyperthreading. Seems to be a must on AMD chips.

2) Ensure that VRcompositor and vrserver both have their priority set to at least AboveNormal.

Having said this, I did end up upgrading to a 2700X which copes with wireless with no issues at all

The wireless adapter uses proprietary compression/encoding technologies from 3 separate companies  (Intel, Displaylink, Vive) - it's an IP minefield

Reading about DisplayLink I suppose they sell only to OEM, something we are not. Will be possible to know if the compression used is H264 or AVC based?

@davide445 I would need to defer that specific question out to DisplayLink, you can reach out to them and see if they're able to provide that specific info to your team.

@Beta_Tester Thanks for the real-world report! Appreciate it!

Will receive the Cosmos Monday, and I already know my GTX 1070 will not allow me to get 100% resolution from SteamVR (probably around 60-70%).

Thinking about future upgrade the best cost efficient choice are the RX 5700 XT or GTX 1080 Ti. No doubt about the 1080Ti, but there is any experience on the 5700XT?

Hmm, I haven't yet. Primarily Nvidia cards personally. 

@VibrantNebula or any of the community here?

@davide445 - We're technically agnostic on this one. One thing to keep in mind is that Steam userbase is ~ 80% Nvidia and that as a result, Nvida users generally enjoy greater VR support and more titles have Nvidia specific VR optimizations and integrated technologies like VRS. That said, AMD also has some desirable proprietary VR technologies like ReLive so it's all shades of grey.

Returning on the CloudVR topic, understood for video streaming to the headset is needed at least a 7Gbps bandwidth from the workstation to the headset. 

But what about the link on the other direction, between the headset and the workstation? I suppose need to transmit only the 6DOF data, so need a much small bandwidth. What's the minimum needed?
