Looks like you would need for a Viewport, might work

You need to get the viewport going and the “r.ndisplay” is not the answer as replacment for r.AllowMultiGPUinEditor.
Briefly saw this appear to work but the display was massive. Working in front of an audience and still could not see if this is any faster and its on U.K. configure not USA configured
Who knows hope this helps 5.4 source code cannot be used as this same code is used in nDisplay now
