intel i7 2620M

Hi all pros

I've been reading about maximizing my performance the i encounted sentences like "fsx is more familiar with no hyperthreading","affinitymask=xx tweak doesnt work" and other stuff you may know or not.i run my fsx on my 13' macbookpro early 2011 with i7 2620m(dual core) cpu and 6gb ram.wanted to know : do i have to disable hyperthreading on my cpu? Which affinitymask do i have to use? Any othe tweaks to make my fsx run faster? Is task manager solution (change fsx.exe affinity to only core0 and core1) sufficient?

Thanks
