</syntaxhighlight>

===Test OpenGL ES===
First, change the CPU governor to performance:
<syntaxhighlight lang="bash">
sudo sh -c 'echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor'
sudo sh -c 'echo performance > /sys/devices/system/cpu/cpufreq/policy4/scaling_governor'
sudo sh -c 'echo performance > /sys/devices/system/cpu/cpufreq/policy6/scaling_governor'
</syntaxhighlight>
Start glmark2-es2-wayland:

===Chromium web browser===
====GPU====
Chromium web browser has enabled hardware acceleration by default, supports WebGL, and can view hardware acceleration details by entering the URL chrome://gpu, as shown below:<br />

====VPU====
Play a video in the browser, then use fuser on the command line to view the mpp device node to confirm that the vpu interface is being called:
<syntaxhighlight lang="bash">
pi@FriendlyElec:~$ fuser /dev/mpp_service
/dev/mpp_service:     3258
</syntaxhighlight>
If there is no content output from the fuser command, it means software decoding.

====Check Supported Hardware Decoding Formats====
Enter about://gpu in your browser's address bar and scroll to the bottom of the page to view the "Video Acceleration Information" table. <br />
After playing a video, enter about://media-internals in your browser's address bar to check if hardware decoding was enabled for the most recent playback. <br />
