FS - aka Frame speed.
This mod will display your FPS in a speedy manner, likely faster then any other mod that displays FPS. I heard that it makes my last mod that did something like this, obsolete!
So, all it will do, it display the FPS number at the top left, in a non-obstructing way. Sadly, as of now, and as of time constraints, I did not have the time to put in a lot of work for configs, where you can configure the colors, and where it shows on the screen. - This will likely happen in a future update!
