See if reports gpu utilization with this:

while true ; do
gpuuse=$(nvidia-smi -q --display=UTILIZATION |grep Gpu|sed 's/ //g'|cut -d ":" -f 2|cut -d "%" -f 1)
echo -n $gpuuse" "
#test $gpuuse -gt 1 && echo "higher" || echo "lower"
Anyway, you can monitor the gpu use on little cpu cost (0%cpu on an E7500@3Ghz).
It would be nice if this could be added to PTS, as a nvidia specific test.
Vsync: enabled (without vsync you have always 100% gpu)
App: glxgears (that is not a benchmark, but in this case it IS)
Maximized as a frontmost window: gpu=20%
Fullscreen and window unredirected (so effects enabled): 11%
