fps

is this a good way of finding out my fps?

if not can u point me in the right direction?

/* called duriong initialization(sp) */
bool initTimer(){
QueryPerformanceCounter (&ClockStart);
QueryPerformanceFrequency(&ClockFreq);
return true;
}

/* fps **** /
QueryPerformanceCounter(&ClockStart);
/
drawing /
DrawGLScene(); // Draw The Scene
SwapBuffers(hDC); // Swap Buffers (Double Buffering)
/
updating logic /
logic();
/
fps **** */
QueryPerformanceCounter(&ClockFinish);
ElapsedTime = ( (double) ClockFinish.QuadPart - (double) ClockStart.QuadPart ) / ClockFreq.QuadPart;
fps = 1.0f / float(ElapsedTime);
sprintf(buffer, “Fps %f”, fps);
SetWindowText(hWnd, buffer);

you might want to check 20 frames and do
20.0f/ElapsedTime,
that way you reduce the impact of the time to call QueryPerformenceCounter and it gives you a better average for you framerate

I usually average over one second, like this:

int frames;
double t, t0;

frames = 0;
t0 = glfwGetTime();
while( 1 )
{
    // Get time
    t = glfwGetTime();

    // Calculate and display FPS (frames per second)
    if( (t-t0) > 1.0 | | frames == 0 )
    {
        sprintf( titlestr, "My Program (%.1f FPS)", (double)frames / (t-t0) );
        glfwSetWindowTitle( titlestr );
        t0 = t;
        frames = 0;
    }
    frames ++;

    // Do rest of main rendering loop...
}

glfwGetTime() returns the time in seconds as a double.
