Stuttering, Small freezes and framerate Issues

[jens]

It is likely the stutter is not fixable on your configuration, it is below the minimum requierments and even if meeting the minimum it should be expected to not have an optimal experience.

Another day, another test(s):
Test #1: modified .cfg (StreamBufferSize="8192") - new profile - new game - custom graphics settings -> crackling sounds, massive frame drops even on the main menu, stutters;
Test #2: modified .cfg (StreamBufferSize="16384") - new profile - new game - custom graphics settings -> crackling sounds, massive frame drops even on the main menu, stutters;
Test #3: modified .cfg (StreamBufferSize="32768") - new profile - new game - custom graphics settings -> stutters.

Previous tests here.

Specs:
i3 540 @ 3.06 GHz
8 Gb RAM @ 1333 MHz
ATI Radeon HD 4670 w/ 256 Mb
Seagate Barracuda 7200.12 500GB SATA - 179 Gb free.
Fragmentation: 1% in 3 years. I've never done a defrag. And Mac OS X doesn't need to.

I'm out of ideas.
