I want to deactivate core i1 hyperthreading in the bios to play a game that saw only 4 cores.
Basically, will I really lose performance in games by turning off while knowing that I'm on XP?
Or can I make it automatically turns off the launch of the game in question?
An idea:
Combine the process of the game with the CPU 0 2 4 6 and leave your hyperthreading.
In this way, the game does works than 4 cores, but the CPU will handle rotate the treads on the 8 (which are only software).
And how do you do this? Is it serious to have to disable hyperthreading? Does that risk of heating more/less? Eat more / less?Quote:

Normally you will see the use of these cores fall, but with the CPU hyperthreading optimizes the "filling" of each core, the cores "logic" will not be at 0%.
According to the Intel specs, the physical cores are the first, if I recall correctly.Quote:

Not exactly, hyperthreading Technology is a physical core appears as 2 cores to the OS. But the hyperthreading will optimize the filling of the cores to "split" the applicant or by cutting 2 process at the same time for all the transistors operate.
So by selecting 0 or 1, it does not change anything because the CPU will send some of the work to one or the other, and fully automatically.
I take as evidence my experience on my P4 hyperthreading, and from what I saw at Intel is always the same principle.
