To let you know the characteristics of the computer where the test was run, here is a table with the hardware of the computer:

Part	Description
CPU	11th Gen Intel(R) Core(TM) i7-11390H @ 3.40GHz
RAM	Micron DDR4 16 GB @ 3200MHz
Storage	INTEL SSDPEKNU010TZ (1 TB)
GPU	Intel Iris Xe Graphics G7 96EUs

The next table show the results for multiple resolutions running at standard 30 fps as the framerate and the following pipeline:

For average behavior:

gst-launch-1.0 videotestsrc ! "video/x-raw,width=${W},height=${H},framerate=30/1" ! videoconvert ! qtoverlay name=main.qml ! perf print-cpu-load=1 ! fakesink

For limit behavior:

gst-launch-1.0 videotestsrc pattern=black num-buffers=1 ! "video/x-raw,format=YUY2,width=${W},height=${H},framerate=30/1" ! imagefreeze ! videoconvert ! qtoverlay ! perf print-cpu-load=1 ! fakesink

Results for average behavior
