This addon is a very simple FPS meter. It shows your current framerate and your ping(optional). No background, just a simple numerical FPS display.
It's default position is in the top-left quadrant of your screen. You can move it around and it's position is saved when you exit game, switch character, or /reloadui.
It comes with one slash command:
/fps - Toggles the visibility of the meter
Configuration is handled through the in-game UI. Press ESC and it's on the left side of the screen.
Carbine's default way of showing FPS (ctrl+f or alt+f1) was too obtrusive and I hated not being able to move it and alt+f1 blocks the currency display and cannot be moved either. I wanted something that was small enough to not clutter up my screen and could be moved around anywhere. Thus, SimpleFPSMeter.
