Game is becoming unplayable

emgo2  My point was that it has to be something with your particular setup.  If it was the game itself, others, including myself, would also be seeing many of those things.  Given the number of things you've mentioned makes it difficult to narrow down the cause of your issues.  And you haven't indicated that you've done any troubleshooting on your own.  So, if you want to get your game to run smoothly without the things you described in your initial post, you have to give more information so I or one of the other helpers can help you get it fixed.  While what you've posted is good info, all it basically says is you are having a lot of lag which can be caused by a number of things. 

So, what have you done in one or more attempts to fix the issues yourself?  Have you done one or more repairs?  Have you tried starting a new game to see if the same things happen there?  Have you tried creating a new user folder?  Have you tried adjusting your graphics settings?  Are your graphics drivers up to date?  All of these things are things that you can do yourself to see if you can clear up the issues you are having.  

Hope this helps.
