I would prefer to be quiet about this but since I have a background, yes FPS transitions are a particularly needed feature on deathrun servers.
Let me explain, each type of fps has its own characteristics.
If you get 125 FPS; You can run fast / When you jump, you fall fast to the ground
If you get 333 FPS; This will help you when you try to jump to a far place, also when you try to jump somewhere it will be slow and when you start jumping you will see that you are moving heavily.
In Deathrun, we use it when jumping to the tracks or to finish the map short in special areas.
We call these rooms "Secret"
Believe me, I say it with all my heart because I have a 144Hz monitor, when I try to get 125 FPS, I can feel the screen stutter.
Getting 333FPS on this server won't help anyone because instead of jumping with 333 FPS, you can jump as 125FPS. The problem is that if someone wants to go out of the map, they can go out again at 125 FPS. If you want to limit FPS, limit such FPS.. You need to ban low FPS like 1FPS or 30FPS.
Footnote: This is not a cheat, I think it should be at least 250 FPS instead of 125FPS.
Footnote: 333 FPS was never considered a cheat for me, at least as far as I learned from deathrun server
Footnote: Everyone's problem is in this video every time a new round starts. Automatically makes FPS 125
Footnote: And it does this at the beginning of every round, I do not press the button to change the FPS.
