Connection problems are caused by lacking internet connection, disturbance in the connection or just plain shit that has been stacking in the computer. Best advice is to run various cleaning programs such as ad-aware, tuneUP and so on. Also, some firewalls can cause conn probs aswell or background programs such as anti-virus.
I play FH2 on low-medium settings and it does not lag at all. I have only 1gig of RAM and my workhorse is GeForce 6600.
Pretty much the main rule to remember about FH2 in its first release is that it does not lag any more than BF2 vanilla or other mods, such as PR or EoD2. If you can run BF2, you can run FH2.
ok thx i try some of this suggestion i hope it works and my pc is very clean.
