Lost For Words...Need help with rubber banding..

Heres the Deal, I know theres alot of post about rubber banding but its gettin to the point that I can run Hardlines/Wow/Crisis On max settings but cant play rust.

The deal with the rubber banding.
I have 30meg internet
Reinstalled over and over
reinstalled drivers
steam
verified catch and integ of game
fire wall is off.
Ports open

Anything else I can do?

Specs

also, is it consistent between different servers, or only one the one specific server?

If you have problems on all servers, the problem lies with your ISP.
If not, the server you’re playing on isn’t good enough. Even the best specced servers have problems on high popularity servers, that’s why they tend to wipe more often.
