I like the advantages from hyper-threading when it comes to high processor usage. In my 3DMark2001, I see a 400 point jump when hyper-thread is enabled. Plus, I really can see overall performance of my system when hyper-thread is enabled as well. A game such as Generals where there isnít a need to hold down any one key, I can crank the resolution all the way up and details set to high. Also when using applications such as, SolidWorks or converting and burning files, I see and feel no slow down when hyper-thread is enabled. The only time I see a change is when I play first person games, such as; Unreal 2004, Counter Strike, and Splinter Cell, where holding down a key stroke is a must. So I turn off hyper-thread when I game. But the down side is that it does slow down my system a bit, so I canít take advantage of the ďextraĒ processor.
This is such a weird problem and I have no clue what it could be to cause such a issue as this is. I have tried so many things, such as; changing RAM, upgrading the BIOS, looking at both Microsoft and Intel knowledge base for clues, to even messing with the character repeat and delays both in the BIOS and in the control panel. I have made a little difference by adjusting the repeat rate, but nothing that solves the issue.
