Hyperthreading: CPU under Full Load? Is HT Enabled?

Hello! I am having some computer frustrations this week.
I have an inten 2.6GHz HT processor, and as far as I am aware, HT is enabled...
"With Hyper Threading" Appears on the intel splash screen during startup.

However, my Windows Task manager has only one bar graph for CPU usage. (aren't there supposed to be two?)
My CPU Usage is perpetually at "46%"
Looking at the Processes, it says the System Idle Process is using 90% of my CPU.

I have a clean system, as far asI know, I have no adware and trojans.

I suppose I want to know if this is normal. I have been getting poor performance out of FEAR, and reducing my graphics quality causes absolutely no improvement, so the performance bottleneck must be elsewhere.

I have 1GB nice RAM, and a GeForce 6800.
 
Is Hyper-Threading enabled in the BIOS? My guess is no, if you only see one graph. System Idle Process should take up all or most of your processors cycles when it's idle....hence the name System Idle Process.
 
i think task manager has its HT stuff hidden by default (but not sure), an app like Everest can reveal ur cpu spec.
btw hyper threading a big thing, sure it sounds nice, sells more cpus, but it doesnt really give you much advantage, no wonder it is not present in the core2 products
 
If hyper threading is enabled in the bios then you should have two graphs side by side in the task manager.

Thanks for the help!
It turns out there was a glitch in my Task manager. The CPU Usage graph wasn't updating at all.
By changing the refresh rate, everything started showing the readings I expected.

Click to expand...

Actually, there are plenty of rumours about, saying that HT is going to be present in future Core2 processors... Possibly the 45 nm ones.
And no, it doesn't give you that much of an advantage (although, things like DivX encoding can be up to 20% faster with HT), but it doesn't cost much extra either... so it's still a good deal :)
