Hi,With the tweaks ******* has given me, my FSX is running very smooth. I followed most of the suggestions and felt that setting my AffinityMask to 14 made a difference.Now I read about software add-ons that help allocate cores to certain processes. Without the AffinityMask tweak I probably would have shown an interest. But is this utility really a great tool?Menno

If FSX is running smooth, I wouldn't bother.If you need a good process, priority tool use Bill2's Process Manager. Its fantastic and totally free.http://www.softpedia.com/get/System/System...s-Manager.shtmlSteve

These tools are pure money making as affinity can be set with windows tools, by freeware or as you said in the .cfg (which differs a bit from doing it with the other two possibilities). None of the first two will raise the framerate and none of them all needs an investment.If you feel about setting up the flight sim to some cores and to others not, then go for it and test - no buying of such "marvelous" software necessary and I'd say that some guys are always trying to play with the myths about performance gains, especially in the FSX patronage.Maybe they offer a test version, would be fair before some dollars change their owner.

Yeah just be aware, the AffinityMask tweak that ******* recommends is setting the FSX engine's *internal* use of the processor cores, where the terrain fiber threads go and things like that - utilities like this Multicore Environment thing on the Avsim front page cannot touch what goes on internally within FSX itself. All it appears to be doing is allowing you to assign process affinity and priority, which is a totally separate thing. You can already do this (albeit in a less pretty manner) through the normal Windows Task Manager or through a utility like Sysinternals' Process Explorer.I find this claim that utilities like Active Sky or REX, SB or FSInn and so on are somehow using up tons of CPU power and hurting FS performance to be rather dubious. The CPU utilization on those utilities is very low on my machine when I've checked it while flying.

Thanks, I really value your opinion.Menno
