Since I installed Metro 2033 I can't play it comfortable because constant lags. I was looking for solution and I found only other people problems about frame drops. My problem is different, it's about micro-freezing while frame rate is still in constant value. The most strange thing about that is that I have these micro-lags also in main menu (very rare). Lags, like screen is frozen for less than half a second, getting worse (a lot of such lags) when I'm shooting enemy or people start to talk in the game.
My FPS is around 110-120 FPS and my PC config is rather good: Windows 7, 8GB Ram, Intel i5 3.1Ghz, Radeon 7850 so I believe it can't be a problem to have better graphic card or CPU. Am I right? Recently I bought SSD disk because I thought it's disk problem, but no success. Any advice what can I do more?
I uploaded video on youtube to show suchthis annoying issue (with slow motion as well to better noticemake it easier to notice). Here is the link (watch in HD):
