The QML part is mostly there +to set things up and the benchmark will fill the graphics pipeline with enough +stuff to make it suffer. + +**Note**! These tests are only designed to be used with the sustained-fps shell. + +The purpose of these benchmarks is to give an indication how how much one can +expect to put on screen, and to decide how big the screen can actually be. +Especially in the embedded space where a low end chip may have to drive an HD +display, these tests can help to illustrate if the GPU is up to the task or not. + +Run them in --fullscreen to get the right numbers. 1 means your in trouble. 2 means +you can manage with a lot of work. 4 and above and you should be good shape, GPU-wise. + diff --git a/benchmarks/manual/gputhroughput/blendedrect.qml b/benchmarks/manual/gputhroughput/blendedrect.qml index 6fa2e00..cd0d2c6 100644 --- a/benchmarks/manual/gputhroughput/blendedrect.qml +++ b/benchmarks/manual/gputhroughput/blendedrect.qml @@ -1,5 +1,7 @@ import QtQuick 2.0 +// Stacks x number of alphablended rectangles on top of each other. +// Rough test of fillrate.
