FPS Unlockers are banned, if you were caught.
Your run will be Rejected!
FPS unlockers are not a bannable offense according to a Roblox mod. It was said during one of the RDC's, maybe the rules have changed since then but i used an fps unlocker and capper during one of my runs for a different game and it was accepted. Rules for this game may be different from standard roblox rules but as long as you don't show a fps counter going over 60/61 then you're fine.
Yeah, some rbx src ban fps unlockers because they can slightly alter game physics. For some games this doesn't make a difference (at least one different enough to invalidate the run). While FPS unlockers are not a bannable offense to Roblox, "However, a year later during Roblox Developers Conference In 2019. Adam Miller, VP of Engineering at Roblox clarified that no one will get banned for using the unofficial FPS Unlocker. Adam even went on to say, that he “personally guarantees” this. “If anyone is using the unofficial FPS unlocker," some games don't allow them because of the minor-major physics changes and alterations, I don't know enough about LUA to tell you how they change them but I believe that some things in Roblox games are tied to fps, which when the fps surpasses 60-63 they can affect them. Keep in mind this response can be completely off and may not be the reason fps unlockers are not allowed in speedruns for this game, I'm just going off of what I've learned from the way other games work.
I was talking about running with an unlocker, not the roblox rules.
Sorry for the confusion.
Still not allowed, changes psychics - with fps unlocker u can double jump on ladders, also its harder to do wallhops so no, fps unlocker isn't allowed.
