I'd say, snaps on 20, maxfps is okay 76 is fine, and put the set r_clamptoedge "0" back to 1, just to be sure. Also, do u have Punkbuster enabled? (Should be so, but u could try turning it off and on, do save ur etkey first cuz it could get lost)
Running it with administrator? (usually u cant play at all if ur not on administrator with latest OS, but sometimes it just wont send packages fast)
Ur from the Netherlands, so that should be fine, I'm Dutch too and the server is dutch aswell, so that can't be it..
You sure theres nothing running on the background? (Check ur firewall/antivirusprogram it could be connected to the internet 24/7, if I were you I'd turn that off at all times )
If that still doesnt work, add me to xfire: tiropag
and I may have some things for you to run
