Point is I too am feeling that the AF mask setting is largely irrelevant and am flying without it while watching cpu activity.

 

Well, you can certainly make things worse with some masks, the question is can you make things better, and if so, what and under what circumstances? For example, on my system it does appear that using a mask of 249 improves scenery loading with little to no impact on frames when flying in clear conditions over hi-res photoscenery. On the other hand, if anything this mask seems to have a bit of a negative impact when flying in the same conditions over Orbx country.

 

But I certainly haven't drawn any hard conclusions, nor do I think this is a huge magic tweak or anything - heck I'm generally not even much of a tweaker. Just something to play with a bit if you feel like doing some experimenting.

I hear you. If I go with no AF (no HT) setting my cores are maxed all the time. Best situation seems to be with no AF and HT enabled. But that causes a CTD for me in FSX (high overclock) . For now I'm using AF = 2 (no HT) so only the 2nd core is maxed. Cheers jja

Affinitymask 14 with HT off work wonders on my system. I set up my tweaks according to Kostas guide, when I tried to remove affmask I got alot of stutters and Opus DHM effects are useless whithout it on my system.

So I think this tweak is very useful and a performance booster when used in combination with the other tweaks from kostas guide.

Same here, for a quad CPU.

Yep, it'll do that, and worse! Again, if you moderately to heavily OC, HT on is a BAD idea. If you're going to push clocks, HT should be turned OFF in the BIOS. There's no question and no ambiguity about that!

It would be nice to have the performance monitor tools mentioned in the intel article so we could see exactly what the threads were doing.

"moderately to heavily OC, HT on is a BAD idea. If you're going to push clocks, HT should be turned OFF in the BIOS." I have a 4.6 overclock with HT on and notice no ill effects can you explain why this is so bad, my overclock is rock solid best I have ever had with this new Gigabyte Z77 board, all my other Gigabyte boards with OC were not dependable up too now.

And my build is 100% stable at 4.9Ghz with HT ON.

Hi yah Efrain hows it going, wondering if I turn it off it would help me in some way as I ave done this in the past and found things to be generally slower what an amazing hobby spend thousands of hours just to get it running some what decent lol CRAZY.

OK, my bad; that was a bit oversimplified. If you've fully stress tested at the clocks you're running with HT enabled and it's been stable and not running near thermal limits - OK. OC'ing to a stable level with HT disabled and then turning HT back on without stress testing is not so good.

 

Efrain, your profile says 5 with HT disabled. Did you throttle back to 4.9 to re-enable HT and if so did you find that a good tradeoff for FSX?

 

Scott

Thanks Scott

Oh my bad, Scott. I haven't updated my profile to reflect the change.

 

As for the trade off, oh yea!!! I've been saying this ad nauseum for the past few weeks. I am able to run TileProxy at 30cm resolutions @ 30FPS rock solid ever since I went to HT ON. At 5.0Ghz and HT OFF, it was stutter city and even 1-3 second pauses! Completely unflyable.

 

The 100Mhz drop from 5.0 to 4.9 was well worth it IN MY SETUP. As always, YMMV.

I never really understood the logic of depriving FSX of some of your Cores, even if its usage of them is not completely optimal. I always got best results by allowing FSX to have everything I could give it, commanding peripheral programs off of the main core using a 3rd party program, and then running an external frame rate limiter to eliminate the performance spikes.
