So CDT you promised me improved loading times but i don't see anything being faster, loading times even got worse.
If that sentence fits to your current situation, please read and do the following steps:
1. Due to the fact that ns2 doesn't have a digital signatur many anti virus tools don't trust it. This means the look extra caution into any file ns2 loads.
They will basically analyze every file ns2 loads into the memory. As ns2 now uses multiple threads to load this can combined with your av cause alot overhead at your pc which will make it "turtle" slow.
So please make sure ns2 is set as trustworthy application in your anti virus softwares settings!
2. Defrag your HDD (not SSD)Why you should defrag your hdd from time to time[geekgirls.com]
I personally recommend Defraggler["www.filehippo.com]
for defragging (made by the same devs as CCleaner).
Just analyze your partitions with it and defrag them if they are over 5% framentated this will not only speed up the loading of games but only your system start ;)
3. If the above steps didn't helped you please contact a cdt dev or open a thread in the technical support sub-forum of UWE[forums.unknownworlds.com]
