That shouldn’t be the case at all. Are you using 17.2.3? Older (16.x) versions from over a year ago had the original render display disabled, but that did more harm than good for some games, so it was axed quite a while ago. Presenting the original image on the monitor doesn’t cost performance.
If you see no image on the monitor with the current vorpX release, something is wrong. In that case it would be great if you would a create a trouble shoot data archive in the config app and send that to support |at| vorpx com, maybe it contains something useful. Thanks in advance.
