Stuttering, Small freezes and framerate Issues

[CalinTM]

So, I'm one of those who don't have stutters normally except for some very small ones mainly when walking into new areas of the same map. However, I tried the fixes:

1) Normal Steam: Piano scene -> 2 small stutters
2) Stutter3 Fix: Piano scene -> 1 small stutter
3) Stutter4 Fix: Piano scene -> Perfect

1) Normal Steam: General small stutters level 1 -> many
2) Stutter3 Fix: General small stutters level 1 -> 1 stutter (piano)
3) Stutter4 Fix: General small stutters level 1 -> Perfect

OS: Windows 8 x64
GPU: Nvidia GTX 660 Ti
CPU: Intel i5-3570K
RAM: 8GB
SSD: OCZ Vertex 2
Sound Card: Asus Xonar DG
Launcher Settings: High

With vanilla game i have the same things, but with patch 3 or 4 the game is now perfect, i had tiny stutters but they were very annoying and made the game unplayable.
