Quad cores...

I used to have a 2.5 Ghz dual core, but now I have an AMD phenom 940 Quad core OC'd to 3.5 Ghz, and... with the samce graphics card (it's a 9600 GT OC2, yes it IS 256 bit) I am actually getting lower FPS than before. Isn't there some kind of .CFG input to make FS use all 4 cores? If there is I need help finding it, I use vista.
 
I believe FSX should, but if it isn't, you set it like the following in the FSX.CFG:

[JOBSCHEDULER]
AffinityMask=15
 
What OS are you running and how much ram you have there....


Vista SP1 fixed the extra core problems..XP never had that problem..

I am running Vista SP1 with 3 Gb of RAM, same as before, I did the affinity thing in the config and set my FPs lock to unlimited, that gave me 20 more FPS, now I have 30-40, but not on Extra high, which I'm shooting for...
 
Are you running your power settings on High and not the low or even medium settings? By default Vista only uses UP TO 50% processor power when power setting is set to low.
 
More than 2 cores usually won't give you more fps. In fact you can see a small fps drop when running FSX on 4 cores instead of 2.

The 2 extra cores in a quad improve loading times significantly (by a 30-40% depending on the graphics settings in FSX) and also make the sim more fluid. There's less chance that you'll see blurred textures and missing autogen when travelling too fast over dense areas.

And don't expect to get playable FPS with all sliders maxed even on high end pc.

Nope, I'am at the high or, preformance setting. Oh and Some1, I didn't really know that, well, my birthday is on Friday and I'm thinking about buying myself a little treat, maybe I'll get a GTX 260 core 216. Wonder how that'll be.
 
I replaced 8800GT (a bit faster card than the current you have) with GTX 275, and saw about 15% FPS increase. It's not much given the fact the new card is more than 2 times faster (theoretically :) ). Plus when playing FSX it's much colder than when playing other games, so it shows that the GPU isn't heavily used by FSX.
 
How much lower FPS are you getting? Perhaps an updated BIOS may help. But be wary....
What does a program like CPU-Z show your processor speed to be at?

FSX really never concerns itself much with Video power...


What is your exazt ram you have I Dance???? Make-Speed -Bios set up for it? ( Timings)


PLUS...FSX can and will perform better manytimes with your Scenery and Autogen sliders at 3/4....Not 1/2 ..So push up scenery a notch and see too !
 
AffinityMask=14 moves Fsx off the core the os uses and onto the remaining 3 cores. Seems to work for me.

Well, unfortunatly, it does, after upgrading GPU's a while back I got a 15 FPS boost alone, from a 8600 GT to a 9600GT OC2
 
Yea, but a frames boost in FSX( from a vid card upgrade) has nothing to do with how clean and smooth things are..


I ran SLI 8800GTS for a while, and my frames were typically at or over 100..But it sucked whenever it hit anything heavy..Like a med size airport with light traffic, or a cloud, or some sunshine, LOL
 
According to what I have read you could have 7 Cores!! but FSX will only use two, no matter what!!!!:kilroy::kilroy:
