First off, I've got Combined Ops from steam and I used the worrom tool to install dayz with zero problems and also installed the beta patch. I launch the game by clicking the "launch beta" button on the worrom updater. Everything comes up normally but once I get to the server list everything is very laggy and hard to navigate. After choosing a server and joining I see everything load up seemingly fine but when I get into the world I experience very heavy lag/delay when I try to walk around. After about 30 seconds I get a message say that I've been kicked off the server and I'm returned to the server list. Obviously this seems like a problem with my computer not being able to run the game but I've played several recent MMOs and I've never had any problem...I can even run them on high graphic settings in most cases. I was chatting with a friend who was also playing in one of the servers I tried to join and he told me that it said "Signature Check Failed" next to my user name, I wasn't sure if that could be a clue to what's wrong or not. Also, his game was running smoothly so that rules out any server issues. Sorry for the long read, any help would be greatly appreciated! Update: I ran the can you run it tool to check my computer specs and it says my processor needs to be at least 2.5 GHz but I've only got a 2.2...everything else is fine
