Steam updating slow
Corrupted files can also cause a multitude of other odd game bugs.
To fix corrupted game files, you can have Steam validate the game’s cache on your system.
One trick you can use is setting Steam.exe’s CPU affinity instead – when you launch the game through Steam, it will inherit Steam’s CPU affinity and launch with the correct CPU affinity.Windows doesn’t “save” CPU affinity between sessions – when you close Steam and reopen it, it will use its default CPU affinity settings.Some old games may also have graphical issues with Steam’s in-game overlay – the screen that appears when you press Shift Tab while in a game.However, these download servers can become overloaded – if games are downloading slowly, you may want to change your download server.You can view each download server’s load on the Steam Content Server Status page. To change your download server, click the Steam menu and select Settings.
