Measuring FPS

Newbie & Debugging Questions
#1

So, I’ve been going back and forth between incrementing the FPS control variable by one second and just setting it to the current time when the FPS gets updated. I don’t know which to do, or why. Incrementing it by one second reports a silky smooth 60, setting it to the current time reports between 60 and 63. I asked on #lwjgl (that’s why the code is a pastie) but nobody answered. Help?

Setting lastFPS to the current time results in a time leak. You should always be incrementing by 1 second.

Oh and you should be incrementing the fpsCount variable before the if statement because you need to count that frame as part of the second :wink:
