Infinito3010: to improve loading that would be the last thing to do is clear your cache.
Well every file in your cache is checked every time the site tries to load and it compares the files in your cache to the ones it wants to download = time delay.
So therefore for every new angle you are going to hit from , there is delay checking your scene files and then delay to load the ones WGT wants.
How big will your 'offline cache' get?
How many, superfluous files do you want to keep? Which ones are they?
Anyways, Helps me out. I rarely get meter error and I load up pretty quick on an 8032/384 KB/s connection (slow by most standards)
