Hi *******,first of all many many thanks for your great work and your very clear explanations!I have a couple of questions which I hope you can help me with, and they concern core allocation on the i7.Let's leave all the rest fixed for the moment. And let's suppose that we have hyperthreading enabled.Since in such a configuration the 'virtual' cores are the odd numbered ones (1,3,5 and 7), I assume that in order to replicate the situation you suggest for the Quads (that is, soft affinity = 14) we should tell FSX, via the AffinityMask setting, to use cores number 2,4 and 6. Is that correct?If it is, then the value for the mask should be 84 (= 0101 0100 binary), which would be the hyperthreaded i7 equivalent to 14 (=1110 binary).Actualy I tested the above out on my i7 (below the full specs), and it seems to work quite well. I got a great improvement in frame rate when compared with the 14 setting. This should depend on the fact that if you put FSX load on virtual cores, it does not perform good, I assume...Assuming the above is correct, my next question is: would there be any advantage in switching hyperthread off and using 14, or is it better to leave hyperthreading on and use 84?Comments/experiences from other readers wery welcome too, of course!Thanks a lot... I have another question into the same topic, but I'll leave it for later in order not to create confusion... :-)EnricoMy Specs:CPU i7 940 2.93GhzRAM DDR3 6GB 1600MhzNvidia GTX470 1280MBWin7 64 bit
