If you have already done all the actions mentioned above and none of them worked to reduce lag/latency in Rust, or even, you want a “more definitive” option, we recommend using a program specially designed to reduce lag in online games. The program we recommend is ExitLag, one of the most used proxing/tunneling in the world (including by professional e-Sports players like Fallen). The program is paid, however, it is possible to create an account without having to enter your credit card details to test it for free for a period of 3 days.
