Word Not Allowed,I have Windows 7 64 with Intel i7 CPU X980 6 cores 3,33 GHZ . Will you please advise my "Affinity Mask" numberThanks

If you tell me whether your Hyperthreading is enabled or not, then I can tell you for sure.

Word Not Allowed,How shall I know Hyperthreading is enabled or not? Here is Core info from Task Manager.THX http://img841.imageshack.us/img841/5540/capturecorepng.pngSorry,this is more larger picture. http://img220.imageshack.us/img220/5540/capturecorepng.png

Yes it is enabled

Correct Affinity Mask for you is then 1364. It means using Core 1-5 as Miss Agron said, but 62 would be in the HT-disabled environment. With HT enabled, use 1364 to use all non-HT cores, since FSX doesn't use HT. If you insist on using HT-cores too, then 4092. If you disable HT in BIOS, then 62. Good luck!

Thanks to both of you for giving me such valuable information. I only use this computer for FSX. Will I select "4092" ?

I dont think it would make much difference. Experiment. Best way for it. Experiment with 62, 1364 and 4092. Whichever one gives best results, stick to that one.

Thanks

Di, please, no misinformation:Using 62 in HT-environment is going to cause a 6-core CPU to use 3 cores in total. 62 means 000000111110 in binary (sorry if I missed a zero!!), which means Core0 fibers, Core1 main thread, and only one thread for textures. That isn't an optimal solution for a 6-core CPU.And yes, 62 or 1364, it's gonna make a HUGE difference in sim loading times!Go with 1364.

Okay thanks for clarifying!

Word Not Allowed,Thank you. I am switching to 1364.

Can someone please tell me what AffinityMask I should use, with HT off & on? I have 4 cores & I use Bojotese's cfg tool, my specs are below.

You don't have 4 cores. You have 2 cores and 4 threads.Hard to say on dual core CPU... I would probably leave it out. Or set 5 for HT on, or 3 for HT off. Both cores in use. You gotta tweak your FIBER_FRAME_TIME_FRACTION.

Thank you Word Not Allowed:)"You have 2 cores and 4 threads"......yes..... I was so tired yesterday after 10h of tweaking, reading & fps hunting....man it really got to me!FIBER_FRAME_TIME_FRACTION is not in my fsx.cfg....but it should go under [Main] section right? what values should I use for tweaking?Will try your suggestions thanx:)

Google it, or search here. There are virtually hundreds of posts on FFTF.

On your dual core with HT. If you are running DX10 mode use AffinityMask 9. If you are using DX9 use AffinityMask 13 and enjoy slightly shorter load times and better texture loading.
