Multi Core usage in SP1:http://blogs.msdn.com/ptaylor/archive/2007...ork-in-sp1.aspxso its a bit more than textures on the other cores since SP1, its a combination of DEM, terrain texture synthesis, and AutoGen Type I batches. SP2 fixed a bug in scaling beyond 4 cores, and added AutoGen Tpe II batches being performed via threads on multi-core processors.

Good information from someone who really knows. Is it true that FSX does not benefit from hyper-threading?

correct, FSX recognizes physical cores only. our testing, before Nehalem-class SMT, showed using logical cores actually slowed processing down.

Agreed. Good to see you in here.Since we have you attention, do you have any idea why we get low FPS with some add on scenery and Acceleration and not with SP2.The ones I am particularly think about are some Imaginesim scenery.They are fine during the day but they won't work at night. For now, people know there is a problem but I have never heard what it is. The only thing in that list that could relate to night lighting is the meatball.

if other scenery works at night, and others dont - thats usually an indication its add-on specific and not an engine bug. and no, I dont know what might be causing ImagineSim scenery to exhibit this issue. sounds fixable, if they dig in.

Great to see you here around sir :-)

Phil just missed being around us 'cool' Flight Simmers. :(

Or end-user standards for FSX. I view Acceleration as the "FS10.5" version of FS. It contains an SP2 that is "different" than the stand-alone SP2, and I feel it should be the first "addon" any serious FSX user should buy. Let's face it...there isn't going to be an FS11, so why not get your current FSX up to the latest and last version there is going to be? Then the addon developers could start producing addons for the FSX + Acceleration only, using the Acceleration SDK, etc. There is going to come a time when the developers quit making addons for FS9. The same thing COULD (and in my view...SHOULD) apply for FSX without Acceleration. It would make everyone's life a lot easier. Heck...Acceleration is cheaper than some single airplane or scenery addons for FSX...a lot cheaper. Why not just get it and get it over with? Before a couple years from now, where it might cost you an arm and a leg on eBay?
