FIX for Win7 i7 sluggish performance

[Mr Pras]

So far so good. Thanks Mr. Pras ! Helped my stuttering in Fallout 3 immensely.

You're welcome

Have any of you tried setting the max to say 25% or 50% and see how that works? My thought is your dual threaded games will not have their cores park on them because the value limits how many can. But you still might get the power saving core parking has to offer?

Just a thought.

Thanks for sharing that! I had a similar thought, but didn't try it yet! I thought that the way windows chucks the threads around to different cores will probably cause some sluggishness anyway.

As for games, I always manually force them to particular cores 0246 or 02 in most cases. This forces them to specific cores, so they don't park anyway.

Honestly, I'm not seeing a problem leaving them all unparked. I haven't noticed any battery-time drop at all, although I haven't used it so much recently (the battery I mean).

Hmn, I've read through the thread and I'm interested in trying stuff that has been said. But before I do that, I have a few questions.

What is 'sluggish' performance to 'non-sluggish' performance? How to I determine this?

How can I access powerCFG? I've tried typing it in command prompt but it appears then, in a blink of an eye, disappears.

Thanks!

Sluggish for me, was the mouse pointer and general snappiness. Things like windows updates, scrolling, moving the mouse pointer. All had a delayed feeling as if they were reacting a few frames after doing it.

Also the mouse refresh was very slow, like 15 fps or something. After trying several things to try and force the CPU cores to be more responsive, I had to conclude that it must be a hardware thing.

Then one day I found this and the answer became clear. Perhaps it's only on the mobile i7 or i5 but they seem to be quite aggressive on shutting down the cores. Once that stopped happening, the machine feels much faster and I have a 60fps mouse pointer (or 59 in the case of this monitor).

While windows moves even a single threaded application around all the cores, semi randomly. This would cause the cores that were being shut off to have to wake again all the time.

Forcing some applications onto certain cores can help, but with the main system processes like moving the mouse and redrawing a window it seemed to remain sluggish.

Anyway, once you change the setting (assuming it works for you) you should see that things become snappier and feel more responsive. There are slight improvements on the benchmarks I ran, but mostly it's a lower overall latency rather than a higher throughput.

If that doesn't make sense, just try it and see. If you don't feel comfortable about it after changing it, just change it back. I'm quite sure it's safe and can be changed back easily enough.

To use powercfg, first type cmd (and press enter) - this opens a command window that you can then run powercfg and see what it says! This counts for all command-line utilities

Here is an animation table I made showing you the comparison between smooth, lagging, choppy, sluggish, and slide show.

I don't know if I am going to laugh or to feel insulted. To be fair, stupid question deserves a stupid answer.

First, I think it's a good question. Because, many don't use the correct term, which makes diagnostics harder. Beside the animation took 2 sec to do... it's so easy to do these kind of stuff in Flash.

I also think it's a good question! and the animation does accurately represent the different terms regarding slowdowns.. better than my torrent of words probably No insult was intended by anyone.

This fix helped give me more consistent performance in PS2 emulation, particularly Fight Night Round 3.

Just looking around for core parking information. Stumbled on some additional information. Wouldn't it be better to remove the Attribute entry from the registration, so that the core parking option would appear in Windows Power Options?

I'm not sure what you mean, can you give us some more info on how to do this?

I thought that would be better at first but then some one else who tried this said it didn't give them the same results as the first method did. As soon as they went back to the first method they noticed the good results in their game.

When you do the changing attribute method, only the minimum number of parked Cores as a percentage is able to be changed and is shown in the Advanced Power Setting as opposed to the minimum and maximum so maybe that is what the issue is. Maybe it is not as clear.
