openCV - imshow at 120 fps

Question

I'm working with openCV GPU processing a video file at 120 fps. My question is: Can I display the processed images at the same frame rate? When I'm displaying images using imshow the fps decreases to 20~30. Can I display these images faster (up to 120 fps)?

Thanks

You will have to make sure that your display (LCD, Monitor, screen, etc) can really redraw at 120 fps first. Even if the display runs faster, some computer systems limit the update rate.
