I have not had time to fly any but maybe I can get in some time tonight. Also, if you Google "windows 7 core parking" there is a ton of info on what turns out to be an old topic. I never heard of core parking until a few days ago. I was sleepy last night searching this stuff and gave up but noticed one post that said Microsoft supposedly issued a fix also.

Ive never understood the whole power options menu for a desktop its not like most PC's that much power. Maybe our overclocked FSX rigs do but no most PC's so whats Microsoft'S point in adding this stuff?

Maybe it's about saving energy?

For laptops I can see the point but I didn't notice an increase in my power bill when I built my PC.

Core parking is a feature that applies only to Hyper-Threading enabled CPUs (i7). The OS 'parks' unused HT logical cores to reduce energy consumption and heat. It does not apply to non HT CPUs (i5 etc) because physical cores cannot be in a 'parked' state.

 

This 'fix' (disabling core parking) is reported to give good results reducing micro-stutters, if applied correctly. That happens because Windows core parking implementation seems to be too aggressive to save energy. Also the transition from 'parked' to 'unparked' state takes some time and in effect produces micro-stuttering and lower performance.

 

I would enable it only in a "high performance" of "gaming" power profile, leaving the "balanced" profile as is, to decrease power consumption in normal use.

 

It definitely applies to FSX also, as in every other game/simulation.

My i3 shows cores being parked.

Yes, because i3 also uses hyper-threading (just dual-core though).

Any CPU that uses HT utilizes core parking.

I used the tweak and it helped I noticed a 10FPS increase no lie I have a feeling windows was shutting down a fair number of my 8 cores.

I would need some convincing, given the difference between frame rate and processor rate. Frame rate is typically less than 100 Hz whereas processor rate is some 3 GHz. That's equivalent to 30 MHz per frame.

Just reboot a couple of times without changing anything and come back to me if result is exactly the same.

 

When you make a change in the PowerManagement for that session Powermanagement will be turned off.

 

 

btw a 10FPS increase in P3D means it`s about 30% quicker, if it is true something more than CoreParking must have been wrong on your PC.

Above a certain amount of load per core, the CoreParking instruction should not activate because the core is continuously above the threshold.
