Better make sure no ones pulling more than 30FPS too to keep the playing grounds as even as possible.
What you obviously don't know is that the military is receiving information about each players statistics when they compete online. By forcing a common experience they are able to better identify the exceptional talents which will then be recruited into the top secret program known as ARSID (Automated Remote Soldier and Intelligence Division). This will be the future of warfare and conflict resolution.
Here is some footage of the program in action which was accidentally leaked to the public by a dumbass contractor. The footage was quickly framed as a movie using the idea of limited hangout to deflect suspicion.

So to summarize, you need that 30fps cap on that wall, you want that 30fps cap on that wall.
