Raise frame rate problem

I want to reduce resolution of view and scale the view to raise frame rate.
I think I can use opengl function like glscalef() to do it
but I cannot find it in opengles api .
I’m just a beginner.Is it a right way to achieve my purpose?
,or other ways to do it? :smiley:

glScalef() will not reduce the number of pixels being rendered into the framebuffer. Try reducing the size of the window you specify to glViewport() instead.
