Is disabling the noise filter allowed?

My run was rejected because It should start from the menu since load times change upon death but loads don't count so how does that make sense?

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.

Could a run of mine be rejected because of stuttering at the tower(not that it ever happened, I just wanna be sure)? I can't seem to be able to fix this issue, it's not because of recording it happens even if I am not recording.

Is there any way to remove loads on the retail version?
