waitkey alternate

My code is already slow and processing takes some time once some frame is captured and processed from camera. When I use imshow ( "name", processedframe ). i don't want to wait even for 1 ms and continue to next loop. If I don't include waitkey(somevalue) after imshow the window is gray. Is there any solution for this? or i must use waitkey to display the feed correctly.

you must use waitKey() with imshow() (no, there's no alternative)

(also, the 1ms invested there will most probably not be your bottleneck. profile more carefully, please)
