when running FSX in windowed mode, press ctrl + alt + del, go to performance.
you will notice that one core is doing alot and the other is more or less idle
this can be fixed very easily

simply go to the processes tab
find fsx.exe
right click and go to set affinity
deselct cpu 1
then close the affinity window
go bk to the winow and reselct cpu 1
now when you go to the performance tab u will see the load is being shared across the two cores

and also if you have 1024mb of memory this is useful
start FSX normaly
while on the flight select screen
open up task manager (ctrl + alt + delete)
find fsx.exe
right click on it and set priority to high
this basicly gives more of your ram to FSX
DO NOT set the priority to Real time because this will more than likely lock up your system.

these 2 things helped my performance just thought i would post em incase people hadnt seen them before

cheers

EDIT: this has only been tested on an AMD x2 im not 100% if it will work with a intel core 2 duo, should do just thought i would add this

I tried this and it seemed to work for me

wow thanks man, anything to get rid of any lag  ;D

Microsoft, AMD and Intel are all aware of the affinity timing issues with 3D applications... here is the permanent fix which will automatically set the timing to one core when a 3D application is launched -and- make WindowsXP apply the correct resources to a dual core processor

wow flymo thanks for this find i will try it as soon as i get back home  :D

Hey Nick!

Sometimes,in my oppinion, it seems, that a System Crash is not so bad.
During the re-installation i found the AMD Core Optimizer and the MS Hotfix by searching for the newest drivers.But its still interesting to read these Posts!

Uh, does that apply to HT processors as well?

Hyperthread is not dual core.. the patch and fix only applies to dual core processors (one slug with 2 cores)or dual slug motherboards that use 2 physical processors.

yeh like nick said before if ur an AMD x2 user make sure u have the latest driver and the optimizer...both i have and yet i have to do the affinity thingy... but it works so.....  ;D  ;D

if fsx uses a single core by default, they shood make a mod which would apply a certain level of physics to the AI aircraft, so that they dont look like they're attached to a rigid path...

maybe in FSXI...

I was told when I was briefed on the project in March FSX would have a VISTA update that would address multithread however that may have been shelved.

Had the software been released for multithread, you guys on single cores would be angry right now.. and it would not have been released on time either.

I know VISTA handles a dual core differently from XP and because of that, FSX, even with without multithread code, will run better on a dual core than it will single simply because of the OS.

There are issues with multithread only a programmer or developer would understand. Most think... "hey, enable multithread and the program will run like a rocket".. That

It doesn't do anything in my socket 370 cpu  :-[

cool, i'm getting 4 anyway...
