Would this be of help for the stutters i get in FSX for the same scenery?
As was explained, many times already, the issue with loading textures is very specific to FS9. FSX doesn't have that many issues loading large number of textures, because it's far more efficent in multithreading.
Of course, providing you *have* a multi-core machine. If you had a single core, then yes, a texture resizer might be useful in FSX as well.
In any case, you can TEST if your stutters are related to the textures size: just LOWER you Max Texture size slider one notch below maximum, and this will force ALL textures in the sim to be at 512x512, which is the same of what the resizer does.
Also, there are plenty of discussions about ways to control stuttering, for example here:
http://www.fsdreamteam.com/forum/index.php?topic=2710.0As suggested there, you can try with different Anti-pop slider settings, and see what difference makes on your system. As already explained, the higher setting should improve stuttering, at a cost of a general lower frame rate. The default setting will probably have the best frame rate, but also much changes for stutters. Basically, more powerful systems can afford higher settings.
And of course, you just can't have it all: if you want to use a complex airport scenery, if your system can't cope with all, you *have* to lower other settings, like AI density, autogen, etc.
