Question Bought new PC, isnt working like it should be..


Oct 5, 2019
Hello guys, im new here on Toms Harware so if ive posted this in the wrong section please forgive me.

I got my new PC yesterday and i was realy excited to get it going.

Anyway i play Rust, yes i know the game isnt optmized in any way but i only get 80 fps ingame, ive done everything the internet says, changed powersettings, latest driver on my GC, settings in Rust, changed my EDC limit... Nothing works.
I get 110 fps on ultra in Battlefield V, isnt that a little bit low? My benchmark results are really good, dosnt seem to show any problems. Its making me go crazy!

My specs are:

People with the exactly same specs have higher fps in Rust, almost duoble the amount.

Why is that, anyone that have a clue?

Thanks for ansawers.
