OK, I’m getting improved results (more fluently view) with these settings:

```
sudo -i

# Disable runtime suspend of VIC
echo on > /sys/devices/50000000.host1x/54340000.vic/power/control

# Set userspace governor
echo userspace > /sys/devices/50000000.host1x/54340000.vic/devfreq/54340000.vic/governor

# Get frequencies
cat /sys/devices/50000000.host1x/54340000.vic/devfreq/54340000.vic/available_frequencies

```

The latter order gives these frequencies:

Then…

```
# Set max frequency
echo 627200000 > /sys/devices/50000000.host1x/54340000.vic/devfreq/54340000.vic/max_freq

# Set target frequency
echo 627200000 > /sys/devices/50000000.host1x/54340000.vic/devfreq/54340000.vic/userspace/set_freq

```

But… what the hell am I doing here?

The effect is visibly, but what is this doing exactly? And is it permanent or will I have to repeat this sequence after each boot? Does this also have an impact to an “ordinary” USB camera inference?
