I've read this from a free download this morning, so I thought I'd post it on here for those that dont know.
Dual core processors: FS9 allegedly doesn’t take advantage of the second processor.
But here is a neat trick how to force FS9 make use of both processors on a dual-core
system: Start Flight Simulator, load your flight in windowed mode, then press
Ctrl+Alt+Del to open the Windows Task Manager. Click the "Performance Tab" and
observe that FS9 is only using one processor. Unless you have tons of other programs
running, the left window will show a heavy load, the right graph a very low load. Click on
"Processes" and look for "fs9.exe" (if you click on "Mem Usage" it should be the first or
last item). Right-click "fs9.exe" and select "Set Affinity". Remove the check mark from
one CPU. Close the window, then repeat the process and select both CPUs again. FS9 will
now spread the workload over 2 processors. You should notice
a marked difference in performance. If this does not work on your PC, contact Microsoft
Support for the optional "dual-core hot fix". |

Thanks for the tip, I'm using dual-core, have seen some info on this, but was told to set it to one cpu, will have to try it this way.
Thanks! TTFN - Ken.
Danger! Part time mind at work!

WingMan, just tried it, very good, I removed my self set fps of 30fps, and before the adjustment I was getting my usual 75fps-105fps, I carried out the instructions you gave, and yes it was showing heavy activity on just one side, back to fs9, and wow! fps over 100 to 140 now. And activity spread over both internal cpus, and neither over 60% load.
Now I wonder, does this have to be done every time I use fs9, or will this now be permanent.
Thanks for the tip, much appreciated. Makes my D-C upgrade worth while at last. TTFN - Ken.

Concur  same for me. Left hand window showing a heavy load before I made the adjustment...........
Before.
And after.
This is taking into account that there are 43 processes running.
I dont care too much for the improvement regarding FPS in FS9 due to my machine high spec, I'll still have it set at 30 fps. I'm just glad to know that I can now run FS9 spread across both cpu's with hardly any strain, not that it had any before.
As regards KenTel's question, it appears that this has to be done each time FS is started, but hey !! it only takes afew seconds.  |

To those who have tried the "fix" does it stay that way or do you have to do it every time you fly.

Thank you! That's too bad but better than nothing.
Did it help your FPS very much.

Darn what am I doing wrong?
I have a Pentium D Dual Core and it either does it on one CPU or the other, Not both, when both CPUs are ticked it is only affiliatiing with CPU1 and Cpu is fast asleep by comparison. What am I doing wrong?

So before = 52% total CPU usage, after = 52% total CPU usage.
Am I missing the point here? |

I can see the change, but then FS9 run with a very fast simulation rate, even with the slow simulation rate the speed is very hight.

I think the point is this - the CPU is running at 52%, prior to making the adjustment only one internal CPU was working and was running at 52% but that 52% is now being spread across both internal CPU's and not just the one. You dont get seperate % usages for each of the internal CPU's just an overall % usage. Cheers and Safe Flying

what kind of computer do you have to get so much FPS? |

Can this be done to all system with a duel core cpu?
Does this apply to a my syste, which has
Intel D 940 Duel core cpu
I am ruuning Vista 64 bit and FSX
As when I try to change under performace manager. view two graphs per cpu, It will not let me change it from a single graph.
I've checked my bios and it as mutil core processors enable and two cpu's are showing under device manager.
Thanks in advance

Vista and 64 bit, try, it's hard to guess.
SP1 may do it if you follow the installation instructions to the letter.

Wow! I can't thank you enough for this tip! It also worked for FSX/Vista but I guess it's good for any program that might not be shared equally. |
