FPS Problems - Need help

So, i have an Intel® Core™ i7-2670QM etc and a Nvidia GeForce GT 630M (2GB) and 8gb of ram, but in Rust, i play at 10FPS or less with the lowest graphics and i have friends that have worst computers than I do and they run it at 30 or 60 FPS according to their graphic settings. I dont know much about this kind of stuff, but i need to help to know whats going on, and sry for my bad english 'cause im from Portugal.

Rust is 100% fucked right now when it comes to fps, it’s completely unplayable on even the best gaming pc’s for some, you’re not the only one who has this. just gotta sit tight and hope they fix it soon.
