Thank a lot Informerman,
i ask the same questions in 5 different forums, no one answer, i serch in internet however i was not able to find the video that you suggest, generally zbrush has great support from pixcologic as well indipendent users however i was not able to find any info about this subject, chache can be changed but nobody explain how, thank a lot, really thank for your precious help!
If i can ask, which os are you running? If windows 64 bit, how much ram do you have, how much do you assign to Zbrush?

(it means thanks in my language, italian)
very usefull video however what i'm looking for are info expecially related to 4r4 cause this new version as many new setting performance related
By the way i begun with Zbrush 4r4 since a few months, no experience.

In 4R4despite the usual one found in previous version too there are new setting:
in preferences> performances multitrhreadingOptimizer
in preferences> utilities there is a "memory stress test" and "run memory stress test",
the test in my pc it always fail, probably i do something wrong cause i dont know exactly what these setting are for, how to deal with them.

this is for zbrush 4 r 4 http://www.pixologic.com/zbrush/system
i think what there saying is on 64 bit you can only get 4GB of system ram, so if you have 8 GB or ram zbrush can only go high as 4 GB of system ram, You cant get any higher.

from what i herd, when you start messing with your preferences setting to improve performance
and you over do it by thinking more or higher is better, well it could decrease your performance

you are perfectly right,
i'm not creazy about best performances, i just want understand how the software works from the base cause i repeat no experience at all with ZBrsuh, i begun with it since a couple of months.

Have the possibility to move the cache file to another hard disk than the one used for installation is an operation that improve performances, that i know cause i experiencing it with other softwares that allow such operation, it is an operation that do not harm stability in any way.

RAM: 2048MB required for working with multi-million-polys. 6 GB recommended. (ZBrush 4 is a 32-bit application, but can use up to 4 GB of system RAM)

This is another subject that make me ask the questions,
ZBrush at the end of the day remains a 32 bit application, it allows to assig no more then 4096.
Thank a lot for your help!
