Are any other mods allowed besides texmod, because I think I have seen texmod in some runs, correct me if I am wrong on that.

I was just asking out of curiosity, even if I had mods installed I would clean my game first before speedrunning it.

Is altering the framerate cap allowed?

altering the framerate cap messes with the game physics. It is not allowed

edit: nvm, apparently it's fine to change (although changing fps is mostly negative so idk why you'd want to do it)
