I have an i7 920 rig. Fsx uses only 1 core at 100%.
I have tried the infinity tweak but it still dies the same. Any ideas guys?
 
If there was a way to use more than one core for fsx I'd like to think I'd have heard about it by now. Ask Soya on here or post in the FSX thread, they might know something. As far as I'm aware, you're stuck with single core for the main application.
 
not true - FSX uses multi-cores I'm sure - but its situation dependant - ie it will use the extra cores when needed

make sure you have SP1 and SP2 patches installed though as one of those introduced multi-core
 
You don't get true multicore performance though. The bulk of the application still runs on core0, even if you can offload some tasks to other cores.
 
I know this is a old post but I found a rather interesting post which may help.

Try adding this to your fsx.cfg

Code:
[JOBSCHEDULER]
AffinityMask=14

Using 14 will try to set FSX onto all cores except core0 for a quad core system.

1111 1111 = 15 = all cores used (a quad core has 8 cores because of hyperthreading)
1111 1110 = 14 = all cores used except the 1st one
