Just wanted to post what we did at a local makerfaire a few weeks ago: ACL | Flickr
As for performance, we have not found a way to have it running with MR at 90fps. We’re running an i7, win10, with a 1080 running at 1440p. We even tried using a hdmi capture and capturing on a separate computer. As soon as the MR camera is active/rendering it drops the frame rate. Our “hack” was to have a shortcut to kill or create the camera. So you can at least run 90fps until you want mixed reality.
