FSX.cfg unnecessarily restricting its use of my processor speed??

[Drizzle]

Was doing a little checking of my FSX.cfg file the other day, and noticed this line:

[Main]
...
ProcSpeed=17184

This got me to thinking... I have an i5 2500k processor overclocked to 4.3GHz on air -- which seems very stable (temps between 50-60C with occasional (usually brief) spikes to 70C) and performs generally very well. Even with most of my sliders maxed. If flying in rural settings (the majority of my flying), I can rely on frame rates glued pretty consistently to my target rate of 31 FPS. No problem. Yet, when entering scenery rich areas of ORBX -- particularly the Seattle corridor -- there are times when my frame rate stumbles into the low teens.

So, my question is this: Is that entry in FSX.cfg limiting FSX's use of my processor's full potential? I realize that FSX is an old single-core program that tries to stuff most of its work through just one of my processor's cores. But is that entry in the config file "dumbing it down" to the potential of the 4.3GHz it COULD be using?? I find most or all of my cores maxed out (100% of my 4.3GHz) occasionally while flying. But there are times -- even when struggling with those low frame rates in those especially dense texture areas of ORBX -- when I notice that ALL of my cores are not working at 100%. Sometimes the highest of them might be "loafing" along at 80% or so... (And for what it's worth, my GPU is usually idling at even considerably less than 80% during those times.)

Would an adjustment to that line make a difference? If it would, then can anyone help me understand what the (more?) correct entry would be?

Thanks in advance for any advice,

I'll be watching this thread for I want to know just about the same thing. My GPU loafs at some of those BIG cities and airports. Need to find a way to kick it in its lazy butt.

http://blogs.msdn.com/b/ptaylor/arch...ek-or-not.aspx is the best answer by far!
http://blogs.msdn.com/b/ptaylor/ has the best useful info for FSX across the board. Worthy of a Bookmark.

Well nuts... That's not really the answer I was hoping for. But I do appreciate your insight. At least I can stop hoping in vain... And that resource will almost certainly help me out in other ways, so thank you Don and Froy for sharing that!
