Stuttering, Small freezes and framerate Issues

[plutomaniac]

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
