Robert,
Seem that you have misunderstood my question. All I want is to remove
the FPS limitation in the Clutter.
For example, in the Main Loop of my simple application
while (running)
{
if (desiredFPS is reached)
render
calculate FPS
}
I want is to remove the line `if (desiredFPS is reached)`. As I knew in
Clutter, when construct the Timeline, we have to input the desired FPS,
or duration into the timeline. And I want to remove that parameter to
have Timeline run at full CPU utilization.
In case we can't do that with timeline, is there any animation API that
allow we move a rectangle to specific location?
Thanks,
-Hieu
