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

which FPS? are you using Clutter 0.8?
Clutter 1.0 is vblank-locked, so it will always repaint (and update
the
timelines) at the same rate. if you're trying to see the amount of
frames per second you'd be able to display on a magical screen with
no
vertical blanking delay[0], you can run a Clutter application after
exporting these two environment variables:
CLUTTER_VBLANK=none
CLUTTER_DEFAULT_FPS=1000
or by passing to it these two command line arguments:
--vblank=none --clutter-default-fps=1000
for Clutter 0.8, just exporting CLUTTER_VBLANK=none will disable
vblanking support.
Since you explicitly say full CPU usage implying you are trying to
remove the GPU from the equation, I thought I'd mention that you can
also set the INTEL_NO_HW=1 environment variable, (obviously assuming
you
are running with an intel driver) which will disable dispatching of
batch buffers to the hardware.
Note if you use this you will have to disable picking (e.g.
--clutter-debug=nop-picking) since the values from glReadPixels will
never correspond to an actor id.
kind regards,
- Robert
