May the problem be that I'm using some geometries with PointCache(WSM) and that the cache files are one file per object instead of one file per frame/object?
Could there be a problem loading point caches? because the objects have a grand total of 1.850.000, and the complete scene including those objects have 8.100.724 polygons, so it's not a specially big scene, if I hide those objects the scene parsing is fast, but if I unhide the cached objects then the scene parsing is multiplied and takes those 18 minutes.
The RAM use is always below 75/80%, and this is with the full system working, I mean using firefox, skype and a file explorer working, of course with those objects hidden it's slightly lower, also is higher than what I said in the previous posts because I did unhide some things that were hidden in the scene just to make the debugging.
Cheers!
