Freezing And Stuttering Problems

[tipadomba]

Perform a steam file integrity check. Make sure it's not installed on a very old (slow) hard drive.

When i try to do a integrity check on steam the button is just greyed out so i can't run it. And the hard drive isn't very old.. Depens on what you mean with old? It's a few years but has no problem with any other of the newest games.
