• There is always the potential that applications running on a machine negatively affect the performance of Steam games or the Steam client. If you are encountering poor performance, it might be necessary to investigate other applications on your machine and possibly disable them for testing purposes.
• Verify the integrity of the Game Cache:
  1. Restart your computer and launch Steam.
  2. From the Library section, right-click on the game and select Properties from the menu.
