What is up with this game?

If your game has the delete saved game feature then you already have the latest patch. If not then you dont have the latest patch. And, yes, you should update and get the latest patch since it fixes many things. If after getting latest patch and you still have the problems you mentioned I would suggest a complete and thorough uninstall of the game and then reinstall it again. If that doesnt fix it then I dont know what to tell you. I dont think STEAM itself is the problem with the game. Its the game itself that has all these bugs.

Edit: You dont mention which video card you have but you may want to get the latest drivers for it just to be on the safe side. Some people have found that helped their blink, lag, and stutter problems with the game.
