FSX AI Traffic

Are there any free mods or model replacements to replace AI traffic with that will result in better performance? It is to my understanding that FSX uses full models for AI traffic resulting in large performance decreases.

I have tried my traffic x but it just installed to much I now use WOAI with about 20 to 30 airlines, all the military traffic installed, and even though they are not fsx models there simple and my framerates are better than using the default or my traffic.
After installing WOAi you have to install the FSX ga as once fs9.BGL's are seen it ignores fsx traffic although the cars will still work you can get the FSX default GA here

Dave,
Certainly include it.....
...but no credit needed or deserved as I picked up the 'tip' from some un-recalled source long ago. ;)
Side note: I (and others) also do the same for add-on ac, ...\SimObjects\Addon Aircraft\... with appropriate FSX.cfg entry. Helps keed thing tidy.
