SP1 for FSX is now available. The primary effect of the patch is the ability to effectively use multiple cores although there are other significant improvements as well.

Those of you waiting for improved performance prior to using FSX can now start enjoying a true multicore experience.
The DX10 patch is still in testing but ACES is saying it should be out later this summer.
Well .... I thought it was pretty significant news from a dual core utilization standpoint. IMO, it means that Microsoft is responding to hardware advances in an actual single application. Since I don't mess with other "games" I'm not aware of others that are actually able to utilize multiple cores in the application itself.
I see this as a significant evolutionaly step but maybe I just get excited too easily
