Missed stimulus video frames

Hi,
We use version 2.2.47.
We present visual stimuli created in advance as videos.

We always get warnings of 'Missed X video frames', although the frame rate of the videos is 60 Hz.

Is the solution as simple as getting a more powerful graphics card?
Any other advice?
Thank you,
Amir.

What is the width and height of your videos? I guess a video card with large memory and a powerful CPU can help with it, but it is not always possible to prevent skipped frames for large videos.
