As we know that BGMI and Pubg Mobile has no differences and both work similarly. Same anti hack system work in BGMI too. But there are some differences. Before BGMI Pubg Mobile Ban system and anti hack system work for globally and it was managed by Tencent but now BGMI rights are having by Krafton so the new team works on it.
Are some hacks legal in Bgmi?
But if you want to know that there is any legal hack for BGMI than it is just a myth if you are modifying any thing in BGMI than it will be treated as hack and hack is only illegal. Although FPP config files are also not allowed but it don’t become caught by anti ban system. So if you want to use Frame Rate Config you can go with it.
