Confirming!

Today i'am having this trouble all day. I've changed video quality to very low. And this is my PC conf:

• intel i5 2500
• gtx660
• 8gb ram
• 7200 hdd speed
• win7 64

So, here's a little video, where you can find after 9:00 how game starting to lag. I dont know - can i post links here? So, I'am very sorry if that's not permitted.

Also: I think that problem is in SKS, cause, before i grabbed it - it seems that everything was ok.
